Yeah there is snow on the ground but 14 this weekend, bye bye snow lolYeah, winter is on, eh? Here as well. You guys getting any snow up there? Just a few dustings in town, and the mountains are not covered as much as usual by now. I've got a couple snowshoe treks planned, so hoping it's a good snow winter, or I'm moving up near you!
Head is new? I had my head resurfaced and cleaned and then reinstalled. My car blew blue smoke prior to this work being done. Started my car after and the blue smoke on start up was worse. I was dumb founded the machine shop/ mechanic didn't replace the valve stem seals. I thought this would have been standard practice. As a result I replaced them myself with the head still on and it was not fun. Any ways blue smoke was 100% gone on start up after replacing them.Nah head is new, only happened 2 times that day. Never before never since. Not looking into it any further at this moment

Don't they boil the head to clean it.....I know the head gets hot when installed but wouldn't this ruin the rubber seals? Mine were rock hard.My car's head was pulled for a head gasket and reinstalled for $1800 for the OP. They did not adjust the valves, nor replace the valve seals. On a then - 30 year old engine! I suspect this happens a lot as valve adjustment and seal replacement take skills a level above the neanderthal level needed to replace a head gasket.
The head was sent out to be resurfaced and it was checked for cracks and repainted. There is no one on this earth that would say no to replacing the valve stem seals at that stage. Going forward if I ever have head work done again I'll verify the shop 1st.Supratrbo - a full head disassembly would permit that type of cleaning but for a head gasket a shop would not do that in general. My head shop does - they are phenomenal. But thats my gripe is a shop working on a 30 year old head should replace the seals and charge for it. Nobody wins if the customer pays $2000 and a month later its blowing smoke.
Skipshot - not sure I understand the link between lapping valves causing ring issues. I think someones giving you sketchy info there.
Yep, on high mileage engines that aren't in good shape that's exactly what happened to me.I had a 75 Civic that I did a valve job on and after that it burned oil badly until I did the rings. Of course this just means that the engine was shot and needed a complete rebuild. I did not have that problem when I did the valves on my 7M even though it had many more miles. I guess engine durability has improved since 1975, who knew? 😂
