well, i'm taking out my series II motor (spun a rod bering on the 4th piston and found lots of sludge in engine..eww) and i figure while i've got it out i could do a few mods to make it faster...you guys know more than me, what can i do that'* not too complicated or expensive...i do plan i either gutting the stock intake or just getting a cold air...cept i can't find many good ones......so that'* it...let me know

Fix your upper intake manifold for starters. Info in Techinfo for you. That'* what probably took out the bearing.

Also check the links and look at the different venders. They can help add some pep when you mash the load peddle.

check out intense racing and the performance packages

If you want to go n/a, ZZP has the best cams and rockers.

Good set of headers - right in the same line what Haro posted

I looked at the date on the UIM, as described in techinfo, and the UIM says 2004 on it (the car is a 96), so the UIM was probably replaced, but i doubt if the LIM or gaskets were. The UIM also had a metal plate between it and the EGR valve, to protect the UIM from the EGR'* heat. Just out of curiosity today, i pulled the #1 spark plug and it had white scaly stuff on it, and i just replaced the spark plugs about 3-4 months ago (which the old ones were the same way with white scaly stuff). So then would the problem be the LIM gaskets?

There is no safe date on UIM'*.

Carefully inspect that UIM, replace with an APN kit or a Dillon kit from Bob Dillon here.

Lower intake gaskets should be the new aluminum frame GM design.

Flush the DEXcool completely out of your car and switch to the Prestone long-life Dex compatible coolant.

It'* a 3-part fix.

i know that the UIM failure is a common problem, and the car did have dex-cool in it, (which will not happen again) but are you sure that the possible UIM being crappy is what caused a spun bearing? there was no apparent coolant in the oil, nor did the level seem low. Is there a way to inspect the UIM for damage to see if it really does need to be replaced? i'm not against replacing it, i just want to spend as little money and time fixing this as possible.

what happens when antifreeze mix'* with the oil?? anitfreeze eats the main bearings! that sludge was antifreeze and oil

trust all of us the motor went because of that
