Thanks everyone for the replies regarding boost in park.
I get it now after reading your responses and reading up on the design principles
of turbos.
Of course , have now been struck again with another SDL demon - -
this time the head gasket, the portion that seals the top of the timing case to the front of the head just decided to break ( probably months ago) and vomit oil all over the front of the engine. Fun -fun - fun.
Get to pull a #14 head , can't wait to see what needs to be replaced.
If the head is good, now would be the time to do valves, guides and seals as well as true up the head. I really hate to see what this looks like when I get it torn down.
Thanks again.
Chuck
