Mechanical Adjuster Failed

[bmwpower603]

My mechanical adjuster was worn. And failed. 2004 audi s4 moro blue 6speed 150,015 miles.

Have already done, valve covers, clutch, flywheel, slave cylinder, rear main seal... and much more

If i decide to get the $4,000.00 JHM timing chain kit. https://jhmotorsports.com/shop/catal...us-p-2311.html


Should this realistically last another 100k, WITHOUT having to pull the engine again? (maybe do head gasket?)

[FulhamFTW]

Uh, yeah, you should been fine after that provided your cylinders are in good condition. You shouldn't need to touch that engine again for a long while.

[gcoy]

Do it. Its a good investment. These cars are solid in So many ways.

[bmwpower603]

The JHM mechanical adjuster looks like it can take a beating.

Audi got cheap. Bad engineering.

I would compare that to the, failure prone mitsubishi turbos BMW used on the 07 335i/ 135i

Better materials used. Can go a LONG way.

[Gambatesa]

I have a set of mechanical adjusters with very little wear if you wanted a cheaper alternative. Have pics of the wear

[gcoy]

Yes, The JHM adjusters look Really good. They released them a month after I did my timing service. I was bummed but the new OEM adjusters should last me another 100k.

Do valvetrain while its out. Wouldnt want to pay 4k on timing and have a worn valve seal go bad

how much work/cost is involved with replacing the valve seals? I didn't realize until recently that they are known to fail, once I learned that I decided to at least inspect them when I have my engine torn down for timing but I've also been meaning to look into how much bigger of a job that would make it, and whether or not it's diy-able or if it would require a machine shop or what

[bmwpower603]

Should the FRONT seal be done also??

Is this the correct valve seal kit your referring to from JHM ? https://jhmotorsports.com/shop/catal...2l-p-1285.html

I think I'm going to get Oil check valve, and intake spacer kit. This will also prevent a lot of future repairs. And guide wear..

once all the original timing components/chains are removed there are a few bolts holding the head to the block. You need a special tool to remove the seals. Theres a way to do it with the head still on but will be harder to do than to just take the head off.

yes & yes..also the coolant temp sensor and slave cylinder

And this!!!

PS: while the engines out, headers will make your car a beast!!!!!!!...... might as well.

Ok great!
My friend who is a master bmw technician. Said he would only charge me $2500.00 for engine removal, Full timing, and head gasket replacement.

I think that is really fair. Does anyone know what JHM charges to do this? But they must do so many..

If your BMW master tech buddy does a good job, i'd like to take him up on his offer as well, seeing as that is about $1500 dollars less than two of the three quotes I have received so far.

Keep us posted if you go that route!

[bmwpower603]

Im sure he would be up for that.

He just left BMW about 2 months ago. And has been slow, but steady right now. He can use the work.

I will keep everyone posted!!

Since part of the discussion deals with labor cost.
I was recently quoted $3000 labor for a full timing job where they only pull the trans. I asked how, reply was we can change out most and only need to work from above for a few items. ..does this sound possible and is the quote average?

I've had several independent shops quote a similar price for trans removal and timing service, but most of the high end specialty shops have told me that pulling the engine is the better choice because it greatly reduces the chance of anything being missed or improperly removed/installed/adjusted.

Most of the shops I have talked to will only perform the entire timing system service (full kit) if they are allowed to pull the engine.

[0396]

Thanks for the reply. I think that for the money, its best to pull the motor. To my knowledge, Audi dealership pull engine and trans as a unit and pull trans to access the timing components.

[VinnysS4]

The job can be done with the engine in.....but trust me when i say that it is best to pull the engine. It CAN be done with only removing the transmission, but lets be honest...do it right the first time and you wont have to do it again..that is unless you put oem chain guides in...and then you'll be doing the job again in 100k lol JHM FTW

Sounds about right.
Yes. Pull the motor and trans.

Is that quote including parts, or in addition to parts?

[bmwpower603]

Parts is $4,000 alone..

$3,000 is for labor

That is certainly the low risk approach. My mechanic has convinced me that the JHM Intermediate kit is sufficient. I believe it's the most popular kit JHM sells FWIW.https://jhmotorsports.com/shop/catal...h=21_56_61_240

I get the extra piece of mind, but $2500 is a lot of cabbage.

[bmwpower603]

That depends on if your keeping the car i guess. And if you want to pull the engine once again. For something like the Electrical Cam adjusters
