He told me it was just the head gasket I saw him drive it after and it seemed ok at slow speed (looked very spectacular down the strip I thought it had shit its self)

I saw him tweak the boost before his run which made me think of melted pistons

looked like steam to me too.

Although he had been tweaking the boost....

It was boosting up to just below 8psi, its tuned to run at 9psi. The thing with the tweaking, i changed from an MBC to a bleed valve just before the races. The mbc is too uncontrolable, i would have had no chance on the strip. You get too much torque steer + wheelspin. I had to keep adding to the bleed valve trying to get it to 9psi.

I blew the head gasket in about 3 different places. It actually started using a little bit of water + white smoke the day before, but i wouldnt let that ruin the day. Ive got RAC after all so i just checked the levels before every race.

It was honestly one of the best days of my life, met tonnes of ace people, got some good advice from giallofly and managed to get about 16.7 i think, which im very happy with!

My radiator is from a cooper, never had any overheating problems and its a low temperature running engine even when on the strip.

Cooper is a good unit... A lot more consistent than some of the 'super' 2 core ones...

Head skim time?

Well done not many minis beat beatles yesterday.
What was the beatle disqualified for?
If everything is flat and no cracks etc the head gasket should last a long time!!!!!!!!!!!!!

will it just be the head that needds skimming or the block too?

will get it skimmed this time. how many miles after doing the head do you guys torque it up again?

I might just get a straight edge and check it first tomroow, i think when i did it last time i should have torqued it up a few weeks after, they didnt seem tight enough. When i saw the washer in my engine and stripped it down, i basically torqued the head up, drove to work and then checked all the nuts with the torque wrench again.

Can i just ask, how much of a job is valve stem seals, took me 45 mins to get head off today, then spent an hour trying to work out how the head is all put together, i want to do the stem seals to find out if that random oil smoking at idle will go away, its not done it for a month or so tho now.

You will need to skim the head and or block if they are not flat.
I havnt run turbos long and havnt checked the torque in the past but after around a 1000 miles from my last rebuld I checked the tappets and thought I should check the head first and found that some of the nuts were needing around half a turn.

Valve stem seals are easy just remove the valve springs (with a valve spring compressor) and replace the saels and reasemble.

Just phoned my work and they sell valve spring compressors, will buy one next time im down there

Just waiting to get paid on thursday now, and then ill make an avonbar order. Going to order two head gaskets time time one to take as a spare.

feebs,

You planning on changing to 1.5 rockers or a high lift cam in the future? If so, swap the valve springs for 'high lift' 180lb items. Easy to do now, rather than when you want to fit the rockers!

As you say, get a straight edge on the block and head. Regardign gaskets, insist on the genuine rover headgasket (Payen BK450).

Ordered just now
