New to club and new to the valve adjusment motors. Does anyone here know how to do this?

I just got this car as it had been sitting for 3 years (literally not moved) so I am not sure whats been done and I know valve adjustment is critical.

I need my valve adjustments checked and I know it will be around $500 if I have it done at European Autohaus. I would like to save the money and or learn how to do this if possible?

My slave cylinder just went out so I am getting it towed into European to get that replaced as well as the master.

So far I have done:

- all fluids replaced (except brake fluid and coolant)
- did a tune up (plugs, air filter, fuel filter)
- hood and trunk shocks replaced
- new tires and alignment

Greg @ European said I should get a valve adjustment but I really don't want to spend the money. Any help or advice is appreciated!

thanks :help

Matt???
Does the e34 M5 use the S38 like the e28s?
I'd guess that a valve adjustment would be very similar to even the M30. Jay helped me with mine. It wasn't hard at all.

Yeah E34s have the S38B36 or 38 depending on if it's a Euro Model or not.

Do the coolant and brake fluid. it's not a matter of mileage, but rather how long they have been in there.

I just recently did a valve adjustment on my S38b35. It's a very simple procedure, but I had to use compressed air, a magnet pen, and the tool needs to be "rented". I would suggest signing up for the S38/M88 yahoo group; great people and help. The tool can be rented from them too. I can give you the email of the guy I used, he was very quick on shipping and even sent shims. I will post more if you need, but check out this website. It's how I learned how to do it.

http://www.e30m3project.com/e30m3perfor ... stment.htm

Other great info. on this site as well. Don't hesitate to ask if you need anything, I have a test this evening though so I may not be much help until later.


Adjusting valves on the M20/30 is different, way less messy and just as easy.

I would definitely do a valve adjustment if you don't know when it was last done. The S38 is a pretty reliable motor, but it's sensitive to lack of maintenance and abuse (i.e. not letting it warm up before hitting the high revs).

Did this go down? Have you figured out the procedure yet? Any updates?

An E28 with an S38??? Pretty sure the E28 M5's had M88/3's in them. Either way, the S38 valve job is like doing two M30 valve jobs. It's not hard, just time consuming. If you aren't comfortable, I would pay for it. Valve adjustments and transmission work are the two things I will pay for on a E34.

The Euro E28 M5s had the M88/3s in them while the US got the S38s which are detuned M88s with dual timing chains and catalytic converters.. Also, the S38 valve adjustment uses shims of various thicknesses to get the desired lash setting. These shims are riding basically on top of the valves in seats and are then acted upon by the cam lobes. It's an ingenious solution that has been used for many years, especially by the Jaguar inline sixes.

Indeed. I don't know why I thought otherwise. I knew the M88 was a euro only motor...I just wasn't thinking.

And the shims...oh the shims...did I already mention ITT that I hate valve jobs? Praise the lord for auto adjusting valves!

Nope, the day I was going to take it in to get the valve adjustment, coolant and brake fluid changed I got in to start the M5 and the clutch dropped to the floor. I guess the slave cylinder went out. The seat also went all funky and broke on the inside so it leans funny. Greg quoted me $460 for the seat fix, as well as the slave and master cylinder replacement. My windshield also got a huge crack in it so everything seemed to happen at once! Luckily I have another car so it wasn't a huge deal but it's not in the budget for me to fix it all at once. The goal will be to get some of the things fixed (we will see) and up and running by the EuroMeet unless anyone has any cheaper or better suggestions?

On a positive note I got my NWBMWClub.com decals in the mail and will be putting them on the car this weekend.

For typical maintenance stuff, hit up Brendan (Absent). He'll get it done for a lot less than a shop, and he does great work. I'd have a shop do the valve adjustment, but I'm sure he could handle the clutch work.

The seat twist issue is very common on e34 seats and is easy to fix.

http://bellsouthpwp.net/m/i/miales/seatcablesfix.htm

http://forums.bimmerforums.com/forum/sh ... ?t=1277178

I've had to fix the issue with the seat back of my driver seat (sport) and the headrest of my passenger. I depending on which part of the seat is having issues, it can generally be done without taking the seat out of the car (you will probably have to unbolt it though). The DIYs make a it look a little confusing/complicated but once you get in there and start tackling it its pretty straight forward. So this fix yourself and save the money for the valve adjustment etc.
