TAB & StPike75 Reset Coolant Bomb & Trek through the Valley for Guides to 300k miles

TAB has reached the danger zone of 150-175,000 miles for the M62TU. No significant noises on start up, but realizing the odds are stacked to "when, not if" I have decided to tackle the guides while conducting a cooling system overhaul with Valley Pan Gasket. The cooling system is pushing 80k and the Valley Pan has a weep resulting in an occasional temperature foray to 110 before going back to 106-108. I will be replacing the Valley Pan and upgrading to the Zionsville system. So while I am in there... And as long as I am doing this I might as well do some other things (oil separator, vacuum lines, VANOS, ...).

StPike75 hasn't any cooling system or valley pan issues but did have the "every 5th start" rattle at 121k miles on the iT. That has since quieted with an oil swap to 0w40. The final listing of components for StPike75 may be significantly shorter.

We have decided to go as a team: he will assist me and I will assist him. Not simultaneously as out schedules won't allow for that but having two sets of eyes and hands should make the job a little easier. Not to mention that having two people should make documentation better and easier.

As for the materials I have gone for the FCPEURO kits and supplemental items and will be getting the GAS Master Cam Timing Tool Kit. The procedures are being assembled/condensed/created from an amalgamation of the sources at the bottom of the post and will be attached when completed. As I am expecting to go in August, I wanted to double check with the forum before the procedures so as to avoid the "when I guess I need to overnight that..."

So the questions for the community:

1. are we missing anything in our material lists?
2. anything else while we are in there?
3. anyone in the Northern Virginia area have the various supplemental tools (crank/pulley holder(s), VANOS press, etc)? I say NoVA for geography reference but can work with shipping.
4. (when added) any points on our procedures?

oh man that looks like fun... fluids, oil, coolant, atf for power steering.. sealants... loctight.. beer... and then more beer.. dang, I wish you were on the west coast.. are you planning on doing videos and pictures too?

 

[MKJS]

Giant breaker bar al ah, "Around the M62..." They are not much money, and seem to really be the hot thing breaking the Jesus nut.

That is our plan. Plenty of pics and vids both for our reference and the forums reference/amusement.

On our "tools to get" list. Luckily a HF is near me so will be utilizing that to a great extent.

 

[MKJS]

Going to wade into mine likely... October. Same stuff. Going to hopefully wait until it cools off a bit and also need to collect a lot more parts.

Looking forward to reading all about your adventure!!!

TAB is fantastic, he's been doing all the research!

Luckily, I get to contribute some by having a mess of hand tools.

I do want to throw out the questions of what assembly greases, lubricants and gasket goop we need to gather? I've used honda gasket sealant forever on bikes and the scoobie, but have never needed to seal a 90* corner.

 

[TheAngryBear]

To get organized and ensure I have my parts (and let's be honest, provide a little parts porn) here are some snippets:

Belts and tensioners

Cooling/heating hoses

Manifold

Timing

Vacuum

Valley Pan

VANOS

I also replaced the three (per side) metal hinged cam seals under the vanos housing. I didn't see the check valves that go behind the vanos solenoids on your list but the list is huge so maybe I overlooked them. And, new o rings for your egr pipe where it mates to the head. Mine were in a horrible state. I also chucked the torx bolts for my front intake cover and the ccv. I cleaned the old bolts from my valley pan in the parts washer and used them in place of the torx. The 3/4 drive breaker bar at HF worked great on my crank pulley bolt. I slipped a piece of schedule 40 gas pipe over it and she broke lose straight away. Home depot sells a pre-cut four foot length and it fits nicely on the HF breaker bar. If you have the ability to drop the trans, it's a good time to replace the rear main seal and rear engine cover gasket but you have to pull the flywheel. Maybe new trans and engine mounts. And those pesky o rings between the block and engine mount. I completed mine about a week ago and I have never heard such a quiet and smooth running engine with 180,000 miles on it. Have fun. I look forward to your posts.:thumbup:

Also, if you're draining the block you may want to get another gallon of coolant. I think I read the capacity is somewhere around 3 gallons on the M62 540i. I know mixing mine 50/50 it took more than one gallon of coolant. Not sure about the new radiator capacity though.

Hey Bear & StPike - awesome thread guys. I'm at 128k miles on my '99 740iL - the engine is running fine, but I know that this job is in my not too distant future. Will be keeping a close eye on what you two are doing and for any parts/tools/goop you haven't already ordered. Thanks and once again, awesome thread!

 

[boostmaster]

I don't see Beer on the list.

Also, make sure to have:
1. a charged camera (mine always craps out because I forget to charge)- you need lots of pics. You will not remember where everything goes AND WE want to see the pics too!!!

2. a box of ziplock baggies and a marker

3. some cardboard for 1) punching in long and short bolts in a specific pattern 2) for laying dirty stuff on.

4. a bunch of shop towels (I buy the blue paper towels in bulk at costco)

5. cleaner, degreaser (it's easier to work on clean parts)

6. tap and die set (just in case)


And a tip you are probably aware of, IF you can start spraying the bolts you anticipate will be a PITA- start now... Do some spraying every day. I had pretty good luck with the new stuff from WD40.

Good Luck guys!! (If I were closer I'd come and help)

 

[StPike75]

Boost, yes the stuff that get overlooked!

Some masking tape to mark connectors!

Cleaners+++ would make sense to have a plastic tub and a pressure washer as well?

We may mount a go pro on time lapse, but then the world gets to see all the oopes

 

[boostmaster]

Not sure if you need a pressure washer, just some towels and cleaner to get all the grime and built up gunk off of what you can reach.

You might also consider sending your injectors out for a rebuild as well. I did that when mine was down. Now I KNOW that they are operating optimally. Isn't too expensive and with over 100k on the clock it's not unreasonable.

 

[StPike75]

Injectors - we won't be able to send them away, because we can't afford the down time. We'll need to figure out what basic maintenance can be performed.

Last build I did I was able to rent a SafetyClean machine. Came in REAL handy for cleaning all the parts that need to be cleaned.

sharing the oopses is a good learning experience for the masses...sheesh i wish ida known of the possible oopses when i got mine..made quite a few

bluebee was very generous in sharing her oopses. They provide a learning experience for all, not just the person wrenching on the car.

Can't afford the downtime? I hope you have a second vehicle around just in case.
Trust me that a 2 day project can quickly turn into something much longer... When I did my car (and it's not as involved as yours), I ran into several unanticipated issues which pushed the project by days.

If you have a second car, you won't rush worrying about down time. Take your time and do it only once!

True and while in there we will be Semper Gumby. The "secondary" vehicle for me is the wife's and kid transport so while possible that then cuts into work time etc. If needed might go the rental but planning should assist in overcoming obstacles.

We are also looking at doing some work prior so we have things ready for install. Things like getting injectors from a part out and rebuilding them vs getting new. Same with valve covers and having those powder coated now vice the. 3-7 day most local shops are saying. That gives us time for TAB and can repeat on the items for StPike75 then we will haves "spares" at the end we can make available to others. Planning and seeing what cost vs benefit is as we still have some time.
