Hey guys. I'm hoping you can help me out. I have a 2002 LL Bean with the H6 engine. Went to start it this morning and it just cranked over fast, no start. If you've ever heard an engine trying to start with a broken timing belt, that is what it sounds like. I verified fuel, then spark and both are good. Plugged in my compression tester to the RH middle cylinder and I get zero compression. I don't even want to bother checking the other cylinders because they are such a PITA to get to and I'm fairly certain they all have zero compression also. So what the heck happened here?!? It has about 160k on it and car was running great last night.

My next thought is to pull the timing cover and start checking it out. I'm guessing I have a broken timing chain or stripped timing cog.

Does anyone know where I can find a guide on pulling the cover? I assume I just need to pull the radiator and then I can get at everything?

It's my understanding this is for a newer H-6 but is great reference to see what you are looking at. I saved it from a reply posting from member Cardoc.

This compression things a mystery! Any chance someone took it out for a UN-authorized midnight ride? Very odd; Good when parked then this overnight. :gasp:

As for the JDM engines,~~~ Total cost with shipping was 1142.

That's a good price! Almost cheaper than having a dealer change your spark plugs.....
