Got the Tahoe running again. It bubbled a little in the overflow,after driving it pretty hard,the first time.
I bled it at the cap and drove it mildly,checked the over flow,and it was good. Then I made a few full throttle take offs,checked the overflow again,and it was not bubbling.
When I started it the first time,it would not build oil pressure. I loosened one oil filter and cranked the engine,still nothing. I ended up priming it with a drill ,but it didn't work with the oil filter tight .
Got my gauges installed. Also I connected the alt p terminal to the factory gas tach wire,it worked but way wrong. I then installed a complete diesel instrument cluster, and it works perfectly.
It's just a universal Spectre clamp on. What I really want is a universal filter,that uses steel grateing,like a stock filter. I've ruined a turbo from sucking in wire on a K&N or Spectre. The filter thats on now,Spectre,there is already one strand sticking inside. This filter is not damaged,they are just poorly designed. Pretty much any filter that is made with wire I don't want. I did drive it with no air filter,ran ecxactly the same.
