N47D20 120d no start. Where to?

Recommended Posts

Cleaned then checked for straightness is the standard procedure.

Does that cranking video sound VERY wrong to anybody else???

It doesn't sound like the compression is correct/evenly spaced.

Compression test and check the cam timing??

 

Chocolate biscuit to you Sir (and everyone else that mentioned compression). Cylinders 4 and 3 are ~300psi. Cylinder #2 is 270psi and #1 is 50psi! Acetone soak with ATF didn't help at all. Oddly enough with each cylinder at TDC, there's very minimal leaks that I could hear.

I'm determined to get this going before my 1 year anniversary of ownership. Considered a donor engine but I think I'll do it properly and give this engine a birthday. New timing chains, sprockets and tensioners. Water pump and thermostat. Piston rings (bores look fine, so I don't thing I need to do anything too drastic there). Head gasket and head bolts. Trans filter. Let me know if there's anything else I should tackle. Won't know the condition of the bearings until I have it out.

My wife always says I think I know everything... 🤣

Nice to find a fault... but not as nice when it gets expensive 😞

The anarchist in me likes to find broken stuff. Glad it "softly" died, as opposed to a catastrophic chain failure. Wouldn't have been far off.

However, the rod bearings and Crank appear to be in great shape. I'll chalk that up to the solid service history and regular oil changes.
