ok so i know i could sit down and figure this one out for myself but thought it might be nice to have a team effort (if this results in me ending up with a better finish then i will suffer that )
I bought a plenum spacer many many moons ago from another forum member. The spacer came with somewhat less parts that it was supposed too so for the time being I just cobbled together some bits and got it all sorted temporarily (im sure we all remember the cracked plenum fun). so now i have a bit of time to get the car up to scratch i thought it was a good point to revisit the plenum spacer. so the facts/issues:
- it is a sloped solid aluminium spacer, 7mm back and 10mm front. i found it once, i believe its an american one? but i cant remember what make it was, any ideas?
- it didnt come with strut bar spacing washers or longer bolts so i resolved that finding some that fitted
- it didnt come with a gasket so i liquid gasket'd it this weekend
so the issues i have are:
-air leak on 6 middle bolts, possible casues are
--- the nylon spacers under the 6 towers are already squashed and now leak air round them
--- the bolts supplied are just plain wrong, it was suplied with only bolts, no washers. I have put rubber o-rings with washers onto them in an attempt to seal it but hasnt completely worked.
--- the botls arent long enough in some places so i need new ones anyway, can anyone reccomend a supplier for them? and what type are reccomended, i assume ones suimilar to stock with a large flat head on them are best?
--- is there somewhere i could buy new nylon spacers for the 6 bolts
sorry to type so much but trying to describe it best i can.
Cheers for any help/tips/links
