02 SSEi Rod Knock 1K after UIM/LIM
I find this site and my second post is not a happy one.
I have an 02 SSEi that I bought new!! The car has been flawless for 79K miles. Recently the CAT was rattling and I took it to be replaced. While my friend (who owns the exhaust shop was working) I was making visual inspections. I noticed moisture in the intake area and that the coolant in the overflow was just a bit low. He told me of his wifes Monte and the fact that the UIM/LIM are suspect. The car showed no signs of anything wrong.
Within two weeks I serviced the UIM/LIM gaskets and felt it was obvious they were shot. Repair went like clockwork. I also had to replace vacuum T'* as they were brittle. I used GM replacement intakes and a Fel Pro Upper and O Rings.
After the repair the car ran GREAT....even better than before......one thing I noticed is that prior to the repair the supercharger had a howl to it BUT after the repair it didn't .....I still had all the boost....but virtually none of the howl. Regardless......all seemed fine.....
Fast forward two weeks and my son and I are out running errands. We return home and I hear a knock. I notice that my oil pressure guage is semi erratic. Pressure is low but comes up under load.
When cold the knock isn't present but above idle it is back. Changed oil....no change...not that I really expected it to just "go away".
Seems to be coming from the front of the motor. (pulley side) Pulled both belts today and the knock is still there. I am assuming a rod bearing.......wouldn't think it is the HB,
So now the question......Pull the pan and change the rod bearings?
Look for a long block?
Pray for a miracle?
How difficult is it to pull the pan? Appears that the motor mount on the passenger side also attaches to the pan. Seems I could support the trans and pull those bolts..and the pan bolts..and the pan would drop? Is the seal on O ring?
A mechanic friend thinks I have little to lose by pulling the rod caps and investigating...and changing them as long as the crank journal isn't scored. I believe that it would be hard to imagine that the rod would be knocking with no other damage as a result?
I welcome any comments or advise.
Thanks for the great site.....wish I'd known about it sooner.
I love this car......and have no desire to part with it....up till now it has been a pleasure.
If I wind up rebuilding this....or going with a long block......I want to mod the HELL out of it!! The way I see it there would be little reason NOT to have a bit of fun with it.
