b16 engine overhaul

arcturus · Nov 12th, 2019, 13:25

Moving on from my previous thread, I had compression anomalies in 3&4 cylinders so decided to strip engine and check everything out.
Engine out now,head off and bellhousing and flywheel removed. That allows me to fasten engine block to stand.I had a bit of a problem as the threaded holes in block for bellhouse fixing were not the same as in B20 but solved that problem with some threaded rod from builders merchant which fit and will be cut to size

More progress,got it on the stand now. I had to make up some fixing bolts from threaded rod.The head is off and at first inspection there doesn't seem to be exhaust valve recession,time will tell. Now to start on the engine proper.

Following with great interest.

What were your compression anomalies?

No 1&2 cylinders good compression 3&4 low. Oil test indicated possible rin problem.
See my thread Oct 30

What did the head gasket look like? Doesn't look as if it was blowing as far as water was concerned but the actual surface and the ring around the bores looks like it wasn't sealing as good as it could be. All rather oily/carbony. Head bolts might have been torqued rather low. May not have affected the compression. As I commented about my old B16, my money is on broken rings. Any scratches on the bores that you can see?

Compared to what I am used to (which is not Volvo), looks like quite large valves. And what is the cc's on those combustion chambers?
