Help With Engine Rebuilds
Discussion
Hello i am a newbie to this forum, however i know u are serious about ur cars here so i thought i might join and post a few questions.
right i dont have anything exotic, in fact i own a Williams3 which is having serious running issues. i have been told by a couple of people it seems like the bottom end is going. the main reason i joined is because i know there is actually a North Wales section here which is where i am from and was wondering if there were any locals that would be able to help me in my quest to get the little shit running right again.
basically it runs very rough when cold and have alot of noise coming from the back of the engine block. the noise is a funny kind of tractor noise which sounds worse when u rev it short and sharp when cold.... it also splutters a bit and has trouble idling and a couple of people have suggested wild things but the most experienced ppl i have chatted to (2 who own their own co's) have said that it really sounds like the bottom end is going.... GREAT
anyway i know little about the actual engines like how to take it out but i do have alot of time on my hands which i want to use to nurse the car back to full health. it may seem a bit ambitious but hopefully with a little help i will be able to do it
cheers for any responses Jamie.

Nice car! I'm no expert but doesn't the exhuast manifold come out of the back of your engine? If the gasket was blown or the manifold cracked it might cause some of the symptoms you describe, I think it's the cheapest thing that could be wrong 
The job can be straightforward if none of the bolts shear off. Having said that, if it was the manifold I'd have expected two experienced mechanics to have diagnosed it so it might not be that.

If so, and it is confirmed that the bottom end is suspect, get it up on ramps and take the sump off. Then get one or more of the bearing caps off and take a look, if the bearings on either the mains (crank bearings) or big ends (conrod bearings) are seriously worn i would consider removing the engine and getting the bottom end reconditioned by a specialist who can regrind and fit the appropriate bearings for the crank.
Doesnt sound like good news i'm afraid
