Valve Adjustment Question, Valve Adjustment Question Options

[HerdofCrickets]

So perhaps I'm slightly not overly excited about smashing my hands up there to do the adjustment (ie lazy) but.... I'm about to try my first valve adjustment, is there a reason we don't drop the exhaust out of the way? Seems it'd be MUCH easier without that blocking all the workspace!

Well me too, I can't find a darn thing online about how to fix that so... that makes me nervous! (IMG:style_emoticons/default/chair.gif) (IMG:style_emoticons/default/slap.gif)

Hopefully you are not dropping a valve seat
most likely there would be a significant compression loss in that cylinder that you would be able to detect through a leak down test.

but fixing a valve seat would require dropping the motor, pulling the head and having a specialist that is familiar with aluminum heads on air cooled cars make you and install another valve seat.

this would need to be done before the entire seat dropped into the combustion chamber and blew up the rest of the motor (possible, bend rod, hole in block, holed piston, contaminated oil passages, etc)

most people that actually have a dropping valve seat would consider pulling the head from the other bank and consider having those seats checked at the same time

whom ever last touched the head, could possibly not have the experience required to rebuild the head and seats correctly.... causing one to come loose and putting the other 7 seats at risk for a similar fate.

if they were rebuilt by a known and skilled specialist... you would be more likely to be safe that only one seat is loose and the other 7 are not at risk.

many people will go ahead and fully rebuild the motor at this point... especially if its a tired motor. Sitting for a decade is not good on a motor. but possibly further inspection will show your rings, valve springs and other items are fine and not in need of replacement or rebuild.... and possibly you will need to replace some of those items after 10 years.

an expert with experience, or a a lot of research and careful measuring can help make that decision.





Adjust your valves
then if the noise still exists... don't drive it without digging deeper

I'm pretty sure that when he goes to adjust the valves he'll find "one of these in not like the other"!

If you have to pull one head you might as well pull the other and get it inspected at the same time. Once the engine is out all the other "while you are in there" spending starts (IMG:style_emoticons/default/happy11.gif)
