I really hate the "15 THOUSAND DOLLAR ENGINE REBUILDS SOOOOON" meme

My S38 had bad valve guides, a cracked valve and worn chain guides. I did all the disassembly and assembly work myself, paid for parts and head machining only. Spent about $2500 total.

Thanks for the link to your thread. Great inspiration. To me it seems like pretty basic engine rebuilding stuff. Much less afraid now.

Ofc the price can skyrocket pretty darn fast if you pay a stealership to do it, but when you can do it yourself, its not that bad.

EDIT: Any links to other S38 engine rebuilding threads are very welcome, as well as gearbox rebuilding threads.

depends on how tidy you keep it... http://home.insightbb.com/~todd.kenyon/Chain.htm

you can't swap the bottom one without either cutting a bunch of it off or pulling the head

Is it bad to cut the top bit of the guide off?

[kronus]

they don't exactly grow on trees :)

nice build thread on my28, hadn't seen that before. Any reason you didn't go with b36 cams while you had it apart?

[kronus]

What not easy about changing them? There is no VANOS or anyhting?

Chains and guilds are not easy to change, but not impossible and not cheap... about $1200 in parts and who knows in labor if you paid someone.

The S38B35 engine is not cheap to rebuild... I've seen $12k bills on a basic rebuild. And parts are getting harder to find and more expensive.

They are sturdy cars but rust is definitely a concern. If it's showing any then you can bet there's more hiding in other areas. I agree on the chain guides as well. At the very least get the S50/S52 timing chain tensioner installed right away and check for signs of guide disintegration.

If that's the car and you get it, let me know if you ever decide to get rid of those wheels.

S38 was so pre Vanos think 70's....E28 are very simple but have old style fuse boxes and chassis's were not designed for any semblance of winter duty. Must have reverted back to Ferrous Oxide, shame I like them.

They have been a languishing classic that only recently have started climbing in value.

Only gonna be parts cost thats a problem for me, thats bad enough though.

it's all three. The lower ones more so than the upper one. You can hear the chain slap pretty distinctly if they're worn.

Okay, are they easy to change?
