Not that it matters too much. Any engine where adding 'Radweld' or similar is part of the servise is crap anyway.
You can't give it a very thin coating of a Viton rubber sealant?
(Not a clue if there is a liquid sealant that works for this application)
MLS gaskets sounds like a bit of a pain, really...
Blew out the headgasket on my old 1.4i (Citrën TU3JP4) last fall...
Spent 'a while' replacing it(small garage, had to work with the door open... shitty weather... ) and still only got half compression on several cylinders.
Pulled the head, ground the valves, and got a bit better.
Ended up replacing piston rings, 2 cylinder liners, those little oil-seals at the top of the valve guides and a lot of other bits and bobs.
(replacing cylinder liners is an 'engine out of car' job according to the book. I now know why... It's a pain in the... to do it in-car)
I think I should have replaced the 3rd liner also, because all cylinders are within 0.5Bar of each other, except one, which is another 0.25Bar lower.
(Got to have something to do next fall)
Composite gaskets breaks easier than MLS, but they're also a darn sight easier to replace.
Guess who broke a Torsion rod while out 'doing slow laps' and running in the new parts.
No, you can't replace those rods yourself without specialist machinery.
(They need to be tensioned correctly when installed in the rear axle assembly)
So, a refurb rear axle, new rear shocks, new rear hub assemblies(can't remove the old ones without elfing up the bearins as the races can't be removed without damaging them, and the bearings aren't sold separately. Would have had to buy the assemblies anyway, because I don't have a press to install bearings with)
Even got myself a new pair of brake drums, finished the trailer hitch install, did a bit of work on rust. The usual.
Purrs like a kitten, then growls and goes like a bat out of the furnace.
You wouldn't believe it's an 18year old car with a 240K Km engine in it, any more.
Unless you look at it...
I even learned something new.
That oil-based shocks needs to be extended and compressed a few times before mounting, or they won't actually absorb the shock...
(That was a weird test drive.)
