I can relate to you here....I had just resprayed my car and i left a screw in the air box and ended up with a bent valve and scored seat. After I had recovered from the initial horror i spent £80 in the machine shop, got a head seal kit and I got it back on the road. Didnt cost me much as I did it myself, its not a hard job if you have the space and the tools. Dont get too down about it, just remember how good a car you will have when its all done.

Yes. Thanks, He said it would be around £100 if the head was ok. Not much on the bill really. Will probably have to pay that much for the head gasket. It's just it's off the road again. And I need it!

its ok mate i got to rip my engine apart again, i got bad smoking on over run and its not good. replaced one turbo no point replacing the other becuase all charge carriers are clean. so it must be rings? think i nipped an oil ring on refit

Thats not ok Colt! Hope it's not serious. Maybe new rings? Pain whatever.

its got all new internals, rings mains big ends valve stem seals head gaskets. full gasket sets top and bottom. but the bores was scored even after being honed so its either that or a clipped a oil ring on a piston?

I'd do a dry/wet comp test before tearing it down. It maybe the rings haven't seated yet. How many miles has it down?

600 miles since rebuild

sorry for the thread hijack JJ

Bit of good news. Head is now finished & tested ok. Skimmed & fitted with new guides & seals. One new valve. Block cleaned up properly ready to fit. Just waiting for the head gasket so unless they come first thing tommorrow it's still off the road for the weekend.

Sounds good JJ, where is the HG coming from?

Oldham engine center with the head. He's just loads cheaper than everyone else. But like GSF he souces genuine parts. Don't know the bill yet but it shouldn't be too bad. (He would have said.)

lol he never gives me a price either until its done or parts arrived. he uses payen andother good quality gaskets he also gets oem too if you request them. he is very cheap and well recommended

Head & gaskets arrived today. £200 Not too bad as the gasket set is the turbo one. Springs are ok. It was the guide that was tight. Not sure why. Hope that's it for awhile now. Just about rebuilt the thing. (Would have been cheaper to scrap it & start again. But at least everything's new now.) There's lots of marks in the chamber of No 1 cylinder. Must be the original head. It has a rebuilt bottom end from an early car. Should be on the road again by Monday! And the sunroof works

Great stuff

Got some work planned on mine this weekend too.

i hope the marks dont cause poor compression or smoking

Well it did'nt smoke before. And that was the original damage. Must be why it had a rebuild. (Belt failure?) After another skim it's going to have too much compresion if anything. One plus. The chambers are only about 20 thou deep at the front (were there shallow) So the valves will be that bit less shrouded than before. Should be worth a bit more flow at low valve lifts. (In my dreams.)
