Hi guys

Here's another update.

Ordered some more items from minispares, mainly oil seals and gaskets etc so I can rebuild the engine. My calipers have been received by biggred for a full overhaul.

Before I stripped down the engine I thought it would be wise to do a compression test on the engine 180-170-125-180, so I have an issue! Once I took the head off I could not see any problem with the piston or the bores, so today I thought I would remove the valves from the corresponding problem area and this is what I found!





Part of the head and exhaust valve seat are pitted!!! Any ideas what would of caused this and is it fixable and how would it be fixed. Well at least I don't have to change the piston rings







So I have started putting head bolts back into the block and I noticed that one of the bolts has a much shorter thread on it compared to the others (so 3-4 threads shorter) any reason why this would be??
