So my coupe has been off the road for a long time.. finally got her back home and ready to fix her up. She has had the usual tuning work done to engine (ported, 3 angled, forged etc.) by Barbz many moons ago and was running OK one day and then rough as hell the next.
Still idles but very lumpy... seems to sort herself out under load but doesn't sound perfect... and then you remove the oil filler can to see a lovely puffing of exhaust
Did compression test yesterday -> 50 > 50 > 150 > 150 > 150
Not what I expected... what's the chances of this being the head gasket blown between the first 2 cylinders? I know it is quite uncommon on these engines but maybe more common after rebuilds?
If it is the gasket... what else would i need to do the job apart from the gasket set? (new head bolts too etc.?)
p.s... car has always had low oil pressure at idle too... but again i hear that is quite common on tuned engines and to take the guage readings with a pinch of salt too?
Heres hoping you all come back saying its the gasket!
Thanks in advance!
