OM603 out. Any gaskets to change?

Any known oil leak spots on the 603? Should I bother with the oil cooler lines?

Head, exhaust, and intake gaskets. Has a problem blowing out the gasket between the #1 cyl and a timing chain case...

The ones that are a pain, like the headgasket. Although I think I'll loosen up the cruise actuator to make IP work easier later on, since it probably doesn't work.

If you're doing head gasket, might as well do valve seals while it's off.... I hear they're a real headache to do while the head is on......
While you're doing that, might as well put all new upgrades seals into the IP, and replace all the plastic hoses on the IP... Might as well put new seals in the turbo as well. It's a lot easier to take it off while the engine is out... (ask me how I know).
Look into timing chain and guide rods as well...

if it has the original headgasket, you should really consider replacing it on principle... seriously.

the technology since the 80's is far, far behind that of today's. When you compare the original gasket next to a new gasket, you will understand fully.


With the engine out of the bay, you should take the opportunity to take advantage of the space available. Replace any gasket within reason, the main seals shouldn't even be questioned.

Front and rear seal can't be done in the hole, I'd suggest those, and the main oil-pan gasket.

Maybe not 'ready to go' , but certainly compromised.

If left alone, oil will get into the coolant first (most likely) and oil will begin to foul the combustion in cylinder #1; leaving nasty deposits.

Ignoring a leaky headgasket, even if it never 'fails', could permit damage to the surfaces of the block and head.
