getting my first cosworth on thursday. G-reg sapphire cos 2wd. the head gasket is leaking and i wondered if anyone got any advice or things i should watch out for while replacing it. im a merc truck mechanic by trade so the job itself aint a prob. just didnt know if theres anything to check for in the process. any advice would be much appreciated. thanx. dave

 

Just make sure you time it up by using the right marks on the bottom crank pulley, there’s more then one slot n easy to get it wrong.
Leave the manifolds attached aswell, cos getting at the nuts afterwards is a sh1t.
Good luck

 

cheers mate. much appreciated

 

Yea as said leave all the manifold on and just lift the head off, worth checking the head face to make sure it hasnt been over skimmed, ideal thickiness is 138.68 or more, also worth checking for det marks etc. Main thing is to make sure u undo all the pipes etc cos theres feckin loads lol, things like the turbo oil feed, turbo to sump pipe, water pipe at the back of the head!!!

 

Dave, forgive me for being stupid but how u know me and what car u used to own before the u brought the cossie?

 

i no charles. me and my girlfriend came down and spoke to him in yarmouth one evening wen u and pete were there. i had a white 3-series BMW wen i saw ya then. then i had a 2 litre sierra sapphire with a full combat kit and 17's and now i got the cossie. that any help to ya?

if you have the facilities cut the heads off 4 of the old head bolts and then make two pairs of long studs by welding 2 together.....insert one at rear right head bolt hole and one at front left when replacing head for location

 

Dont replace it with a standard ford one, get at least a group A one or better still if you can afford it a reusable tri-metalic one.

 

I have a memory like a sieve Dave

good to hear you got a cossie now though, also my advice don'y put a standard headgasket on. But a Grp A one on as a MINUMUM....there good for a stage 3 which my car runs.

 

cool. cheers lads. hey smit, i spoke to charles tonight and he told me to tell you i live at the end of his road. he said he had mentioned it before. jog any memories?

dave

i repeat my previous post.
