FOSTA Posted June 10, 2012 Share Posted June 10, 2012 Can anybody recomend a company that offers refacing /skimming for a FFIM /plenum?? I only just noticed this Quote Link to comment Share on other sites More sharing options...
David P Posted June 10, 2012 Share Posted June 10, 2012 (edited) That looks a skim too far. Edited June 10, 2012 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...
SilentAgro Posted June 10, 2012 Share Posted June 10, 2012 Are you 100% sure its not the table? Quote Link to comment Share on other sites More sharing options...
safcdixon Posted June 10, 2012 Share Posted June 10, 2012 Just get the torque wrench on it it'll be fine can hodge not get something like this done for you? Quote Link to comment Share on other sites More sharing options...
hodge Posted June 10, 2012 Share Posted June 10, 2012 That looks to be about 3-4mm out. The flange looks too thin to skim that much off. How thick is that flange? Quote Link to comment Share on other sites More sharing options...
Dnk Posted June 10, 2012 Share Posted June 10, 2012 (edited) Have you not got a straight edge to check it with ? a table top isnt the best way really ! If the table is flat and it is warped that much then youd have to balance out the warp by zero ing each end then you'd be halving the amount you need to take off, the thinner you make it the more chance it'll warp again though.

FOSTA Posted June 10, 2012 Author Share Posted June 10, 2012 I noticed it was warped on the head, so I put it flat on the concrete step so i could see better. It was rocking on the head aswell as the step so its defiantly warped I just put it on the table to take a picture. This sucks! It's factory runners welded onto the aftermarket plenum. So is there anything I can do with this or is it a bin job? Quote Link to comment Share on other sites More sharing options...
safcdixon Posted June 10, 2012 Share Posted June 10, 2012 Could you not get a thin plate machined too sandwich between them making up the difference on the warped side Quote Link to comment Share on other sites More sharing options...
Kaan W Posted June 10, 2012 Share Posted June 10, 2012 Secure a belt sander upside down whilst holding the plenum firmly against it whilst checking with a straight edge occasionaly then feather the edges with a craft file. Use a 80pt paper. If your good with your hands you should find it a doddle mate. EDIT: If you bin i`ll pay for postage so you can use my bin Quote Link to comment Share on other sites More sharing options...
spidermonkey Posted June 10, 2012 Share Posted June 10, 2012 Deffinately don't bin it, I'm sure something could be done with it! Quote Link to comment Share on other sites More sharing options...

Dnk Posted June 10, 2012 Share Posted June 10, 2012 (edited) Are you sure there o/e runners ? they look dfifferant to ones i've recently worked on. If they are o/e then removing the webbing between the runners on each end really wont have helped and would have reduced the castings ability to resist warping by quiet a lot.

mellonman Posted June 10, 2012 Share Posted June 10, 2012 im very sure if you fitted and thermal gasket which are about 5-7mm thick and of a nylon type material you will loose alot of that as it compresses into it Quote Link to comment Share on other sites More sharing options...
Dnk Posted June 10, 2012 Share Posted June 10, 2012 I'd machine it flat and balance out the error/warp along its length to reduce the amount you need to remove. Then bolt it on and give it a try, if it fails take it off and cut the runners off the plenum and then get new oe runners welded to it and leave all the webbing in place.

Yeah I'm wanting to try and save it by getting it refaced but I cant seem to find any companies that do inlet manifolds? I've been looking on google for the last 2hrs but cand seem to find anyone in the uk lol there are a few engineering companies but they don't list that they do skimming or manifold skimming :/ Quote Link to comment Share on other sites More sharing options...
Dnk Posted June 10, 2012 Share Posted June 10, 2012 Its a pretty simple job to do any half decent engineering company should be able to do it, anywhere that re machines cylinder heads would be worth a call. Quote Link to comment Share on other sites More sharing options...

Yeah mate im sure, but they have been cut shorter. They look identical to the runners on my old manifold mate Quote Link to comment Share on other sites More sharing options...

hodge Posted June 10, 2012 Share Posted June 10, 2012 My guess is, the runners havnt been cut evenly and when it's been welded its pulled it like that. Is it the end runners that's bent or is there a high spot in the middle. Quote Link to comment Share on other sites More sharing options...
Dnk Posted June 10, 2012 Share Posted June 10, 2012 Yeah mate im sure, but they have been cut shorter. They look identical to the runners on my old manifold mate Yes i was thinking the same after looking at yours a few times and comparing them to ones i've recently done, do they need to be cut shorter ? the two i've recently done haven't been cut down and i think this is half the problem you have. They are both using the Greddy plenum, ones been welded on and the other bolted together Quote Link to comment Share on other sites More sharing options...

a98pmalcolm Posted June 10, 2012 Share Posted June 10, 2012 I'm sure if you get a thick gasket for it and do it up super tight It will be ok? Quote Link to comment Share on other sites More sharing options...
