89 525i rebuild [project 2]

I started this project a while ago as a HG and timing belt job however once everything was coming off I did not like what I saw oil and sludge everywhere. There was so much it was difficult to tell what was leaking.

Last year I replaced upper lower control arms, and tie rods. Also added eibach lowering springs and bilstien shock and struts. Rebuilt my calipers replaced the rotors and pads added stainless lines and flushed the system.

Replaced the subframe bushings with a homemade puller and a torch. Changed pitman arms ordered some new interior parts. I would still like to drop the subframe assy and get all the bushings back there.

So far I am just removing parts from the engine so I can get it out. the plan will be to have a shop clean, inspect, measure, and check for cracks. So as long as all the parts are good it will get some new seals, gaskets, and rings. The engine compartment needs to thouroughly cleaned.

New clutch and probably more as my list expands my parts washer will be getting a workout as most of the parts coming off are caked with sludge.

I won't be finishing overnight. I am in the Navy and I do sail a fair amount so only when I am home or on leave I can work on the car. I really do love the car it is fun to drive and many of my friends comment how good it looks for its age. It will never be a DD it is just my fun car to drive.

I am not looking to do an engine swap but if my engine is trashed or not worth rebuilding I may consider it. Where I live buying an entire donor vehicle is probably just as cheap as buying the engine from the local yard.

Now for some pictures.

It looks pretty good so far!

You just need to pick up some purple power to clean the exterior of the motor in order to find the leaks.

Just removed some more parts today the hood is ready to come off. AC motor and power steering pump are relocated out of the way all the sensor wiring is ready to be removed.

Talked too the shop today head work is going to be 175 cleaning,decking,valve grind, and tested for cracks leaks and straightness. Block clean is 50 pistons 85 plus another 150 for various parts cleaned. Also said he can look into getting me my seals, rings, and gaskets. I will give him a chance too see if his price is better than Pelican.

Decided on my new rims todayTires will be Goodyear eagle GT or yokohama Avid Invigor

Well I ordered some rejuvenator and cleaner from Leatherique to try and clean up the interior leather a bit. Also did some more engine disassembly took off the head and intake manifold off.

Tomorrow morning the engine lift is coming so I should have the engine completely out in a few days.

Some more photos

The engine lift is all together. Used it to pull the motor today. Put the motor on the stand. A few things to remember when lifting go slowly and make sure your transmission is completely unbolted. I found one still in after I took it out the rest of the removal was easy.

Also for years I have been turning wrenches but I figured with this project I needed some air tools so I purchased a compressor on sale and some air tools these were also purchased on sale in preperation of my project.

Tell you the truth I have to say the I wish I had purchased this years ago. Makes working so much easier.

I get to start the rest of the engine teardown so I can get everything off to the shop before I have to leave for work

Today got the rest of the engine apart it's going the shop on Tues. The cylinder head is disassembled. Basically tore the engine down right to the block. Everything looks good no scoring on cam or crank journals.

Looks like I need new exhaust valves but I may be wrong. The exhaust valves were really black the Intake valves looked much better. I might just order new ones I'll wait to see what the shop says.

Cylinder walls were very clean I need to measure the bore but there was no ridge at the top of the cylinder and piston removal was very smooth. Once I get the measurements and everything is verified ok I'll start ordering my parts.

I will still have an assortment of parts to clean. The engine compartment is getting a scrubbing.

Leaving next week for a couple months for work so I won't be going any further until the Fall as I said I am in no rush and I want to do this right so when I drive it again I can enjoy my BMW as it is meant to be driven.

I have made some progress lots of hours of prep in the engine bay and with the engine as well. The kids have decided they want to help as well so this is probably going to be a real slow build.

Machine shop magna fluxed. hot tanked, decked the block and honed the cylinders. Cleaned the cylinder head and resurfaced it as well and put it all back together I only have to do the valve lash. The flywheel got machined and it is all in my workshop.

Anyway lots of hours put in so far hoping all the prep work will pay off in the end.

Did some more work on the block masked it off and got the primer laid down going to let it cure and give it a sand. Then it will painted metallic black with a clear coat as well.

In the mean time I will be giving some parts a good scrub. Pictures after the block is done.

The block is done have to start working on other pieces but the engine assembly should start this week. Going to pick up the rest of the new parts Tues and later in the week begin re-assembly. Depending on how much time I have other engine pieces will get cleaned and painted and baked to cure them.

Some more work on the engine so far the crank, conn rods, oil pan, and cylinder head are in. I spent most of the day with the parts washer cleaning up some parts.

Working on the timing belt components covers and then finish of the front and get the engine back in the car.

I should put on the air intake while I am at it and probably fuel injectors as well. Hopefully if all goes well it will be sitting in the engine bay this weekend.

I am not even going to count how many hours of work I have into this so far. Just taking my time with everything going very slowly to try and minimize any mistakes. I will be greatly relieved at the end when she is all back together and running.

Actually hours doesn't begin to cover it days would be more appropriate.

I have been looking around the forums. It says the new pilot bearings do not require the felt and the spacers in the crank.

Anyone have there experiences they want to share on this so far I am just installing what came with the LUK kit. It all went together smoothly, but since I have time before the engine goes back in the car any input about this would be welcome.

Thanks

engine is home

Engine is back in the car. Now I will begin attaching everything back together. A good friend gave me a hand getting the engine back in place. It is definitely a 2 man job.

I have to deploy for a while at the end of the month going to be gone for a while so I will get as much done before I go.

I figure it will be x-mas before the first run on the rebuild will happen.

This thread is my record of how this restoration is going, but for the 3 others who commented thank you for the comments and encouragement.

I had to order some more parts before I can continue on any further. Most of the parts involved the electrical system. There were some missing wiring harness components as well as a couple of securing rings for the end connectors.

Unfortunately these parts are stocked in Germany so it will be a few weeks before they arrive at my door. The dealer could have gotten them sooner but I had to purchase package lots of 20. Since I am in no rush and saw no need to incur the added expense I will wait for delivery.

Like I said earlier I am away at the moment and will not be back home until December so the car is on hold again.

So I have been looking at some aftermarket rims. Here are 2 options I was thinking of going with.

Option # 1 Borbet 16"x 7.5 type A

I like both but I was looking for any opinions or experiences anyone has had with these rims.

Thanks

rims and offset

After searching and looking through calculators I am still trying figure this out. I have a 89 525i with 15x7 et 20 rims. I have a set of rims that are 16 x7.5 et 35. The calculator says it will be 1.4 mm more towards the shock /strut this doesn't seem like a big deal. It will be out towards the fender 11.8 mm again there is space with the tire size it says no issues with clearance I will loose 25 mm of clearance. A quick measurement with a straight edge confirms this. However this is with no spacer and I read that wrong offset equals bad handling.

Question then is do I need spacers even though the tires dimensions fit and there is no interference and does the wider tire offset some the difference in the centerline of the tire.

Thanks

update on the rebuild

I have made some more progress on the 89. So far the intake is back on alternator, power steering, rad, and all new hoses. The airbox is back on the engine has oil in it so far no leaks anywhere.

My local parts store sold me the wrong alternator belt it seems to long AC and PS belts are good.

Also was going to change all the fluids in the trans and rear drive but my hex set is SAE not metric so back for more tools I go.

The fuel filter bolt is snapped the last time I changed it I just used a wire strap to hold it but since it is up in the air I will get the old one out and put a new one in it.

A few more miscellaneous items are still required securing screws for the rad shroud.

Pretty close to done but I want to do a compression test before the first start.

Battery is charged up and ready to go in just need to clean up the exhaust system a bit first.

My parts washer got a pretty good workout as did the die grinder and some rust removal techniques.

Thanks for the compliment

More work today exhaust is back on but the exhaust manifolds are getting cleaned. Filled the rad only a couple of clamps had to be tightened. Added oil and it stayed in the block no apparent leaks. Adjusted valve lash 1 more time just to be sure. Valve cover went back on. Need to tension the belts and do a compression check then go for the start hopefully.

Well it is all back together. I had some issues with the alternator and some miscellaneous bits. I got all the parts together and she is all done and back on the road. Just took the first test drive today and I am really happy engine sounds great. The car drives amazing it has been 3 years since I started this project and due to my schedule it has been slow going.

The end result is definitely worth it. The project is not done now after the break in of the engine I am going to do some restoration of the interior and exterior.

Probably rims and tires in the near future so I will put it all on here as I continue to restore this car.

I was pulling my hair out trying to find out why the idle was rough at cold start smoother once warmed up and no issue while driving.

Went to my Bentley manual checked out troubleshooting. Of course they say vacuum leaks, so off I go checking all connections for areas that might leak. All hoses are new and tight so I check TPS with a meter and the readings are off and I cannot hear the click of the switch actauting.

Remove the throttle body and the TPS is not aligned correct so I change that and put it back together now cold idle is nice and smooth and the bonus is the rich fuel smell is gone as well.
