Re: Must have been trying to tell me something

Hi, if the head has softened back, the fire rings from the head gasket will have indented into the head surface, you can have light indentation and be ok, which is why normally you are limited to a 10 thou skim when prepping to fit a MLS gasket, but some heads you can get away with more skimming. th...

Re: Must have been trying to tell me something

HGF, looks like you are getting coolant in the oil and its getting emulsified and going through the engine breathing system and ending up in the TB, if you take the cam cover off, you'll prob find that the breather mesh (if fitted) will be full of mayo. I'll bet one of the 'church windows' in the he...

Re: Vhpd

Hi, you cant shim hydraulic followers, as they run against the cam base circle, You would shim the solid followers, as the clearances would change simply by lapping the valves in, Its a bit time consuming on a 'K' head as the cam carrier needs to be fitted, I had to make new shims for the vvc inlet ...

Re: Vhpd

Hi, yes you would need to convert to solid lifters with the appropriate springs/caps etc and a mappable ecu, the std ecu wont cope. The mgf supercup cams were Iirc285 - 290deg duration, and were good for 190bhp, with the springs I had with my head, valve bounce was @ 8400 rpm, which is why I did my ...

Re: Vhpd

VHPD cams are a solid lifter profile, so no good with hydraulic cam followers,
so you would need to convert to solid lifters and double valve springs as the
powerband peaks at higher rpm.
Also you would need a mappable ecu as the std one wont cope.

Re: Cam pulley

It sounds like you didn't tighten the bolt correctly, I'm guessing the grinding noise was the cam pulley tilting out and contacting cam belt cover, go out a buy a lottery ticket, because you were soooo close to bending the valves, as that pulley was about to come off. You need another cam pulley and...

Re: Mems 1.9

Have you pressed in the inertia switch for the fuel pump?. The black switch with the square rubber cap on it. press it down till you feel the switch click, normally if the car is immobilised, it will start and run for a couple of seconds then stop, this is classic immobiliser arming. Iirc the wire c...

Re: Rev Counter problems.

Hi, it may be a sticking gauge,
the wire you should have is coloured white with a black tracer
from the coil neg terminal.
I would try the gauge in a car that has a rev counter as std to
see if yours works as it should.
