Misfire

Got my car out today had the new quaffie box fitted and str brace and done a full oil service on everything took it out for a drive if you build the boost up its fine but when you floor it and the cams kick in and the turbo getting a misfire I am going to change the plugs and check dizzy on the conetion for the air flow in to the maf is there ment to be a earth wire on there

Run it at night and look for any arcing off the ht leads etc, I had that once and took me ages to find it, or better still change the leads if you have a spare set

Ok will do that just replace the lot Need to get it sorted for the rr day at bobs

How long has it sat ? What plugs you running ? Don't go changing everything at once best to know which component was causing it

Been sat for about 8 months but got a fresh fuel in it I have noticed the cable coming of the  plug for the maf does look like a earth lead

Plugs i would say
What plugs you running ?

All going to come out today and be checked not sure what's in there

Right misfire sorted was the plugs but now it's come up with a new one car is going like shit of a shovel on boost no smoke but on low revs when I let of I am getting white smoke

Isn't white smoke moisture, I.e water....? Have you checked the water levels in the rad?

Has the head gasket been changed?

Just had a brand new rad put on it just been out to car took about a pint of water but xpasion bottle has some in it up to full mark and just checked dip stick and oil filler cap for milk none on there it's only done about 4000 miles since a full rebuild

Keep an eye on your water level for sure, is your heater blowing hot air out?

Will get a compesion tester on it in the morning I think it's white smoke hard to tell when I am driving heater does blow sort of hot air

Sort of hot... Get that tester on it and let us know what it is. Is it around 150/160 psi on the cylinders that's a healthy engine? I May stand corrected??

It's never been the best heater since I have owned the car but only use it in the Summer will put test results up tomorrow and keep my fingers crossed

Pete's right, look for about 150/160 across all four and keep an eye on the water levels

You can't say what compressions will be as it may be a low compression build in which case they may be down on figures quoted.
The main thing is that there's a balance across all 4

If the header tank is full it maybe a few things Scott
1 sticky thermostat
2 weak rad cap releasing pressure, try a 1.3 bar cap
3 turbo problem (you say it seems faster, is there an over boost prob)?
4 blow in head gasket between cylinders or cylinder and waterway

Check out the simple things first

My tank fills up too but don't think I have seen white stuff

LIt's got a brand new mishimoto rad on with a 1.3 bar cap I will pull thermostat out in the morning as car did sit for a while it does smell a lot richer than it used to be just get all the other stuff checked before I put it in for a remap

So after a day of checks and calls to bob it seems as if my arp head bolts are wank and the cylinder head is lifting as compesion was down loads on all 4 and coolant is getting in to the exhaust so in the morning it's new head bolts in and keep fingers crossed once again thanks for all the help bob

They are that the head bolts

I thought stock head bolts were best used over the arp ones ....

He has arp head bolts fitted already when engine was built.

They have now let go as it appears the head has lifted (state normal with the arp head studs)
So I've advised him to try and remove one by one and replace with stock head bolts and if he's lucky he may get away without changing the head gasket unless of course it has burnt across to waterways in which case head gasket will need replacing

So fingers crossed for him

Fingers crossed for you then fella ....

Cheers will have every thing crossed Tom if not I got some late nights before sataday
