Got a BIC performance downpipe, bellmouth
7M rebuild time!
Blown head gasket to say the least... #6 did have coolant in it.
Scraped deck. The block appears to have been surfaced and bored to .040" once before, there are no chamfers on the edges of the cylinders. The timing cover where the head gasket meets was leaking oil from being uneven.
Removed oil pan and oil pump, scraped oil pan gasket. Removed pistons and rods.
Crankshaft out
The crank pulley was hardly tight at all, the thing must have been wobbling a while to wear a groove into the end of the crank and destroy the keyway like this. The cost of repairing this crank was too much to justify.
Got another crank and pulley bolt, still looking for a pulley. Crank had some surface rust, cleaned it up and sent it to Bob McKray Performance to be polished.
Yes it is in the back seat of my MKIV
I have another backseat in much better shape, or else I'd never do this shit.
Down to Precision Cylinder Head, a local machine shop, to get the head resurfaced, new guide seals, and valve job. Block to be surfaced flat with timing cover. Honing will reveal if it needs further boring.
Head after sandblasting.
#6 after honing. This is the only cylinder with shadowing like this, so I've gone with sleeving the one cylinder rather than boring all six cylinders beyond .040".
Now waiting for parts to come back.
