Ag, thanks for the fax. Yeah it is coincidental, but I did everything according to the book and I kepr her clean. Not my first time around engines either. I really don't know what the heck happened.

Check out LKQ for a used L36. Their prices are very competitive.

You typically don't see this in the middle of an engine'* life. They happen very early, or with very high mileage. This like this make me nervous for my 1999 L36 with 170K.

Moving to 92-99 since this is becoming a mechanical thread.

Karl... All I can tell you is I am at 155k and have done nothing short of beating my car to death... I push this car to the red everyday... Maybe not for every mile driven... But I beat on it all of the time... I have been through a nasty intake rupture and the motor lived through it.. That was 70,000 miles ago...

I'm not sure where you went wrong... But it was nothing you did.. It doesn't matter, the engine would have spun a bearing later down the road.. You have an issue that didn't present its self until you started getting on it more.. Nothing you really caused at all..

Not sure what to tell you to find in terms of another motor... You be lucky if you could find a low mileage unit from a wrecker and swap you parts onto that motor... I'd be looking at $500-$700 depending on miles..

Still sorry to see the bottom end went tho, and a bit surprised as well...

Karl, it'* unforunate that you lost your motor. I have a 99 L36 myself. However, I didn't change my UIM/LIM gaskets until about 105,000 miles. I have beat on this car a lot.

I think you should look into seeing if the original short block is rebuildable. If it'* not, then go to the junkyard aka contact Ed Morad and get a L67/tranny.

He was talking about his 50 mile ride home when it started acting up, just as I stated, 1993 SLE.

Now now TWM and Pat.. let'* drop that one

Karl.. That looks like more than metal in there. Looks like some water also. You will want to disect and find where the leak was before putting that lower onto your new motor.

I second a call to Ed Morad. He rocks and will take good care of you.

How much coolant went into the lifter valley when you removed the UIM and LIM? Did you change the oil after you did the swap?

x2.

I wonder if the extra airflow leaned you out so much you cracked a head?
Or if the extra leaning out raised EGR temps so much the new UIM melted?

Do you recall anything strange about the way it ran immediately before the noise began? (knock, hesitation, anything?)

Please let us know if you decide to do some forensics and find the source of the coolant leakage into your oil.

That would be crazy if that happened. Cracking a 3800 head is really hard to do. I would more suspect the UIM.

Default KDG LIM OH SH** WTH did I do..... HELP!!!!!!!!!

Will wren,

When I did the swap there was no coolant in the lifter valley when I removed the old uim. See pics in other post. I have a picture there. SActually here is the pic.


That was when the old UIM came off. There was no evidence of coolant leaking into the engine. I did the swap as preventitive maintenance per an earlier post of yours.

Yes of course I changed the oil after the swap.
