My '95 940 (non-turbo) leaks pretty good from the main seal. My mechanic gave me a great price to replace the seal. However, he insists he should also replace the PCV oil trap at the same time, claiming it might be dirty and causing the main seal leak.
2 Questions:
1) Is there a straightforward way to diagnose a bad oil trap box? I tried the "blow" test, connecting a hose to the top of the trap and blowing and feeling the air come up through oil pour cap. Does that mean I'm good or can the other port be clogged?
2) Can I remove/replace the oil trap myself? I've read the FAQ and some claim it can be replaced without too much trouble. Others say you really should remove the intake manifold. Honestly, I don't see how you can access it without removing the manifold. Anybody have experience with this on a 940? I'm somewhat intimidated by the idea of removing the manifold. Should I be?
Thanks,
Andy
