clean up liquid gasket

pff · Sep 30th, 2017, 22:08

I have the cam cover off for replacing valve seals, all ready to go back together as soon as i get the surfaces nice and clean.
problem is they are covered in orange patches where the new gasket goes.
I hadn't planned ahead so i only had degreaser, acetone, electrical cleaner to try. comes off very very slowly. too slowly.

I read on here a suggestion of traffic film remover. i tried autoglym tar remover, didn't touch it. then again i believe its just petrol and the gasket is supposed to be petrol proof, so doing its job i can't be annoyed i suppose!

any suggestions of something specific (ideally i can pick up tomorrow!)
halfords have 'power maxed' traffic film remover, this should work?
acrylic/silicone remover?
IPA?
varnish/paint stripper?

i see some suggestion of 'aircraft paint stripper' but i can't find it outside of the USA.

volvo suggest a tube of their own gasket remover. the guy that sold me the new stuff didn't offer me any remover surprisingly!

Thanks.

Paint thinners maybe wet a rag and leave it sit for a while ? it will take the paint off your cam cover though if not careful , cam.

use a BRAND NEW Stanley blade and almost no pressure, must be brand new to avoid gouging into the surface.

Paint thinners, actually plenty of things i tried, wouldn't touch it unfortunately.
thankfully i had a box of fresh blades, it was only slightly more tedious than i had feared, held the blade almost parallel to the work but it still occasionally wanted to jump up and gouge in.
it's back together now but it won't start. brilliant.

Can I ask what did you use to seal the cam cover to the head once you had cleaned it?

A tube of Volvo's own sealer is £30+. I was hoping someone knows of something cheaper that works.

I used Loctite 5920 when reassembling my Accord engine during chain replacement (so used on cam cover, chain cover and sump). No leaks when I sold the car four years later.

yes that is the method , it's not sealer it is a hard bonding agent ..

So does that make it hard to remove the cover itself? Is there a technique?

As Loctite describe their 5920 product as a 'Silicone Gasket Maker', is it not advisable to use it?

There are lugs to tap the cover up , once the seal is broken it is ok .
