HELP!!!
I've just put a SRi130 lump in my mk1 astra. Its running a gas flow'd 1.8Se head, 1.8 loom, inlet/ex + ecu, 130 cam

Will this head work on this lump??? - it looks the same head but the piston rings (2 of them) have blown. The engine was supposed to be mint (- I suspect not tho now) but the bloke is saying its because of the head.
I'm also getting 16 bar compression on one of the cylinders which seems pretty high?? - the others are 10, 12 + 6 bar.

mart chucked one of these setups in his belmont and it works fine. he compared the 20E and the 18SE heads and there is no difference (bar the cam)
the compression test shows you have very uneven wear. as you say pistons rings and gasket will cause this
whats 16 bar in psi? doesnt sound tooooo high to me. healthy i would call it ;)

No the 6 is the shafted one. The other two come under the term dodgy... the gasket was brand spanking new... oil coming out the dipstick and clouds out of the exhaust... still quicker than the 1.8 tho hehe!!:D
