Anyone have suggestions on what type of plastic they're using in their intake manifold heat shield gaskets dealies. Ive got one on my ep3 and would like to make one for my e30 BMW and dont really know much about plastics.

 

I would probably do a nylon like 6/6 or acetal or delrin.. One of those should work.. You can also search the net and find out more about each type!

 

The place that did mine on the Eclipse uses Delrin.

 

why not go ahead and get yourself a real sheet of phenolic resin?

 

Good call, Ill looke for some phenolic resin sheets...or delriin if i cant find the other stuff.

Thanks.

 

I cut Phenolic all the time.

 

im sure Nayhow MFG could make you one, or anyone who makes **** like that lol....just send them your stock gasket.....gl

 

Could someone give me some more details of these plastics. Thickness and any codes that may exist. Trying to source some materials here in the UK but did'nt relise there would be so many variations..

What would be the best material out the one's listed above.

Regards

Chris

 

phenolic is supposed to be better for not allowing heat transfer into your intake manifold- that is what i would use. delrin is like nylon kinda, but is has a much better wear resistance (bushings) and is much nicer to machine.

 

Just got a price for a sheel of the Phenolic Plastic and also managed to borrow a brand new Hondata Heatshield for B16 so gonna give it a bash..Thanks Bud.

 

Right, Follow up time:

Just got back from my local Plastics speciallist. Phonelic plastic (Or AT Least the ones they had) would in MHO be too had to get a good seal around the IM. The Hondata Gasket I took is made from something called P.E. (Poly Ehterlene)
The stuff I came away with is called P.T.F.E. ( PolyTetraFluoroEthylene), Industry standard, heat & Chemical resistant. More expensive than the Phenolic stuff but seems more up to the job. Details of this can be found here: http://www.boedeker.com/ptfe_p.htm

Gonna make one in a while and will post the results..

PTFE is teflon, and i have never herd about it being used for anything dealing with blocking heat. Hope it turns out for you though.

 

You can get phenolic resin sheets from McMasters. I got mine there when I made some for the D series motors.

 

Hey Tony, you got any more of those gaskets u made?

 

This Phenolic Resin stuff is the brown hard sheets yer, cos I thought that would be too hard to effectively make a gasket. The stuff I have (P.T.F.E.) seems more upto the job. Anyone got any pictures of one of the phenolic gaskets that have been made by someone on here..

Which type of the ptfe did you use and how well did it work?? Cost?? Anyone ever use grafoil (maybe sandwiched between two oem gaskets) or garlock??

 

I had a hondata heat shield gasket fail on me. It only took 6 months, about 5000 miles. The whole gasket started warping, and eventually the coolant passage way had expanded so much it was below the intake manifold and just started pouring water out. When i took the manifold off, the gasket was warped around every port. Whatever material they used, defintly did not hold up.

teflon is a decent insulator, phenolic is much better. http://www.outlawengineering.com makes phenolic spacers but supplies gaskets for both sides for a good seal - rtv silicone is always an option too

old thread bump. i was going to get them custom made for like almost $200 locally and not have them done for like 2 weeks or more since they were busy.

i've been looking for this kit for my JRSC kit. thanks alot man

 

Same here with the gasket though mine lasted for 40k mi. Can't complain. I still don't like taking off the intake mani. What a pain
