Is there any preventative maintenance other than regular oil changes to prevent "Oil Squirter" Failure?

 

Not sure of any...

 

I have an 02, any way of telling if i have the old or the new jets?

 

All s2k's have the same oil jets, four, in the same spot.

Starting in mid 2002, with engine number 1025386, they updated the banjo bolts that hold them in.

This was the theory for the longest time, I did however find an earlier engine number with the new 4 hole design bolts. I'll try to find the engine# of the car and post it.

 

Oil jets don't fail, per say. They can cause undercooling of the pistons, but only at sustained high RPM driving like on a long highway.

But I have learned that SC or turbo can cause the same piston temps. I've had a motor scuff a #4 cyl right after SC installation. From that point on, the jet bolts are always a pre-requesite.

I had another member loose the number 4 cyl, immediately after SC install, with the old jets. I would have done the jets if I did the job but he did it himself.

 

This pic clearly shows the location of the engine number, on the front drivers side of the block.

It is also found on the white sticker, next to the crank pulley. Looks like his is 1008597. If it's an 02, this engine has the old bolts.

 

so is there any way to upgrade the bolts??

 

Yes, remove the oil pan and windage tray to change them. A high quality torque wrench is a must. Torque is ultra critical on this bolt.

 

I'm glad bill's changing that for me. thanks for the post I enjoyed all the information.

 

Thanks for all the info Billman
