FIPG - What Chemicals Break it Down?

[bgrieger]

Simple question...someone decided to use RTV/FIPG to seal the intake manifolds to each other and the head...needless to say, it's pretty much glued on. Anything that will break it down without damaging the aluminium?

I used spray on gasket remover to get the old FIPG off my oil pan. That and some elbow grease.

having trouble gettin it apart? Get a small flat head screw driver and slow make you way around it carefully prying it loose. it will break loose eventually

petrol/gas will soften it.

Thanks, I'll give em a go.

Yep, gas will do it. So will toluene. Bad stuff though. Funny, I've pulled oil pans 4 times on these engines and never used anything but a regular gasket. Didn't know any better at the time I guess but I've yet to have a pan leak.

Might not be smart to pry with a screwdriver on the intake pleunum and head, since it's aluminum you might cause defects in the mating surfaces which would be a nich nich.

Sharp whack with a soft face hammer should convince it to let go!
(works for many things in life )

True dat IJ. I took apart most of my entire engine using my rubber mallet! It was cool.

I spent 20 minutes beating it with a mallet. Even tried putting a block of wood down to protect the aluminum while I hit it with a 2lb deadblow and didn't move it. I haven't wanted to try the screwdrivers either for the reason listed. Have to try again this weekend with soaking it in gasoline for a bit.

 

[IJ.]

You did get ALL the bolts?

 

[bgrieger]

:icon_mrgr I took a headcount about 4 times just to make sure. No nuts or bolts still attached.

 

[IJ.]

LOL Usually a crack with a plastic faced hammer will do the job!

 

[Justin727]

gosh either people dont know how to be careful with screw drivers or im super f*ckin talanted !!!
CAREFULLY. Done it plenty of times without screwing up my mating surfaces

The worst part is it was a Toyota dealer that did it...I had a boost leak I didn't have time to trace and dropped the car off with them. They said on the invoice they replaced the gaskets for it and the EGR...too bad it was 5 years back or I'd march down to their door about the bill. I will say though, it never leaked again!
