M62TU Head gasket/ Timing guides journal
 
Does anyone have any tricks for removing the heads on a 540i.

I have everything unbolted. I twas told I could remove with the exhaust manifolds in place but I am having trouble wrestling this out because the timing rails are in the way to get the angle correct.

Any tips would be appreciated. There is not much room to remove exhaust manifold bolts.

Thanks in advance.

I looked in the the VERY best of E39 Links and only saw related M54 links:
- Replacing the M54 head gasket (1) & M54 cam shaft (1)

So, when you find a good link let us know which were best so we can add them to the best links thread for future users.

I will let everyone know. This has been a job! I am almost to the halfway point.

I am replacing both head gaskets while I have the motor tore down.

I have to buy a tool to hold the crank. I am going to replace the rails while I have it down.

The problem is this car SPECIAL TOOLS you to death.

according to ALLDATA the Ex will have to come off. You will also need the tools to retime it all, but you already know that... also looks like you have to support the Engine to remove the exhausts... strange.. but thats what the book says.

Well, I got the heads off today.

The passenger side head came off with the exhaust manifold on very easily.

The driver side head, well that with swivel sockets and 2x4's to help adjust the head to get to bolts, I got the exhaust manifold off. Will be a PITA to put back on.

Tomorrow morning they will go the the machine shop.

I posted some photos of the block. The motor had a lot of sludge. The previous owner said he changed the oil when the computer told him to with only synthetic oil. Yuck!!

Help me here.

I see an open engine.

I don't see what Edjack is referring to as (presumably) neglect.

So that I may learn, what specifically in the pictures below is that neglect.

you've been here long enough that you have had to have seen ketchup's sludge thread yes? That is what they are talking about, oil sludge built up in the engine.

I put this in the bestlinks thread long ago:
- Why sludge in the oil cap is an indication of a failing CCV (aka PCV)

But, the pictures look nothing like the sludge there:
http://www.bimmerfest.com/forums/att...hmentid=194131
I thought, in the pictures, there was a "mechanical" problem shown.

Is it just the 'brown sludge' from a failed CCV that is what is being referred to as potential neglect?

well I suppose then it's all in the eye of the beholder. I can see the sludge build up plain as day in the OP's pics.

Well today it was 19 degrees in Houston with the wind blowing at 25 mph.

So I dropped off the heads at

David's Automotive Machine Shop in Houston, TX. They do great work. I have been using them for a long time.

I ordered all my parts. Spent the rest of the day CLEANING parts in the shop.

I need to get the Jesus bolt out. If anyone in the Houston area has a counter hold tool or anyone has an idea building one. Let me know.

When it warms I will drop the pan, break the Jesus bolt and clean the rest of what I can on the motor getting the sludge out.

Yesterday was the fight with the Jesus bolt and I lost. I made a tool holding 2 bolts and I broke a piece of the hub away.

My father and I are making a good tool now.

See photos below. We are almost finished. We just have to attach something to hold now.

This tool will be top class.

Kelley71 02-05-2011 01:04 PM

My new tool worked awesome. I have to go to work now though....

Question??

I removed the lower pan, all 8 bolts to drop lower timing cover. Removed Power steering. All front cover bolts that I could find and this lower cover WILL NOT BUDGE...


Any suggestions?

bluebee 02-05-2011 07:52 PM

Just a quick question ... what's a "jesus bolt"?

repcapale 02-05-2011 10:05 PM

That bolt in that picture with the big wrench on it. Good name. Jesus bolt.

first540i 02-05-2011 11:45 PM

did you remove the water pump for the lower timing cover?
theres another bolt in there

Jason5driver 02-06-2011 03:25 AM

Wow!

Yesterday we finished building the counter hold tool. I will say my tool kicks BMW's A**. My father is a genius when it comes to manufacturing. We welded a steel plate and machined out so a one inch breakover bar will fit. I rested the breakover bar again the frame and the Jesus bolt (center crankshaft pully bolt) broke loose easily. This tool you can do it alone.

I dropped the lower pan. Found the retaining clip to one of my cam to cam tensioners. I removed the 8 bolts under the front of the upper pan.

Today I removed the guide rails (glad I did now), cleaned the surfaces, installed new valley pan and cover, and finished the deck of the motor.

Now I am waiting on my heads, Vanos tools, and will have my valve covers powder coated.

Tomorrow I will change motor mounts.

See photos, thanks for all the insight from all you guys!

Update,

Exhaust valve guides needed to be replaced on both heads. This set me back a day because no one in Houston stocked the guides.

Everything is clean awaiting reassembly.

A head gasket / timing guide job while working two jobs was more than I expected but a great sense of accomplishment when this thing is done.

Changed motor mounts today. Driver side was definitely shot . :thumbup:

I'm jealous!

jamesthebikeguy 02-08-2011 03:32 PM

Ugh, that engine sludge is like no other in their eh?

Would dropping a can of sea-foam in the oil loosen any of that up you think?

Sea-foam worked wonders on the egr, and ccv on my old Mazdaspeed3

Today I spent the day waiting for UPS and Fedex. No one stocked valve guides so my head will be ready at 10:00 am CST. :bigpimp:

But my valve cover were finished being powder coated.

I was told the valve covers must be baked at 400 to release any gases before powder coating. BMW uses epoxy to fill in any imperfections and powder coating has to be bare metal. But for 95 dollars my valve covers look great.

Tomorrow weather permitting I can reassemble the top half until I get my timing tools.
