Title: Valve stem seals
Post by: Nickbat on 12 July 2011, 22:11:55
Wretched things are leaking. Tonight I started the car up outside my daughter school and there's an acrid puff of blue smoke emitted from the rear and wafting up the noses of my daughter's classmates' parents. It makes me hate what is otherwise a great low mileage (35k) Mig. >:(

From what I can gather it will cost shed loads of money to have the fault corrected and, given the value of Migs these days, probably isn't worth it.

One day, the sheer embarrassment of it will get to me. It'll have to go, methinks. :-[ :-[

I've never had the need to look into it, but isn't there any way to do the stem seals with the heads in situ? There are various tools to compress the collet retainers for some engines & I made a tool to fit them on a Ford V6 Colne engine after my Dad forgot to fit them when he replaced his heads. Just a thought as the seals are only about £1 each.  :y

I think there is such a tool, but the job is beyond me (in terms of spare time and knowledge).

The problem, as Daz explained when he did my cambelt the other week, is that despite being an 02-reg, the engine is likely an 01 manufacture, when they used the cheapo seals. They reverted to proper ones in 02. Trust my luck.  ;) :(

well i don't know what i'm talking about but my mate in Australia said he did his by shooting compressed air into the chamber to hold the valve up while he worked on it? maybe he was doing stem seals maybe not!! and anyway it was a commodore! lol

Stopping the valve from falling down into the bore is easy (that's what the compressed air is for - string/cord fed down the spark plug hole is another) the hard bit is pressing the collet retainer down against the valve spring in a controlled manner while the collets are removed.
