EK98 showed up yesterday with his SE. Planning to do a little preventive maintenance. He had the Dillon UIM and Buttermore redcued diameter stovepipe, and all the gasket necessary, as well as valve cover gaskets, new coolant elbow, etc.
To make a long story short, this is one of the first Dillon manifolds with the coolant passages blocked. I ended up drilling two 1/4" 'cooling' holes in the sides to vent any heat that may build up in the blocked passages.
Yesterday'* work produced massive coolant leaks at the elbow. I tore the engine down again today, and found a factory flaw in one of the o-rings on the elbow.
A Dorman elbow was installed this morning along with a drilled (slightly) 180° thermostat. Eric went home with a freshly detailed engine, and a washed car.
It'* interesting to note that his intake on his 98 was manufactured in 2002 (AC Delco) and was already eroding in the EGR passage. His coolant elbow was also quite literally DAYS from total failure.
The next time we get together, we'll be doing a water pump (it doesn't sound happy), foglights, and repairing his trunk latch.
Not a bad weekend considering what we learned and found, and the fact that we tore that top end down twice.
