This is Teds '99 SLS Seville with only 70k on the body, the engine vin, matches the car.

Head gasket failure can happen at earlier stages than predicted, as you will see in this case.


OK, here we go!






Alright, here is some insight on our thoughts. As you can see here, this is a serious Rats nest We see this quite often and this one is exceptional! As we take apart a Cadillac we can see how well or well not it has been taken care of.

As you will see, this car has been neglected.



In the above photo you can see silicone around the timing cover, this was the first sign this engine has been out of the car and apart, but to what extent?




In this photo you can see what we were expecting, as I began to to remove the head bolts on the right bank alone 5 bolts did not touch the surface of the head. When I tried to pull the bolts out of the heads, they were locked in by the Serts you see in the photos, our fear is true that this engine has been somewhat repaired at one time.


Some have asked me, how do I know that a Cadillac or GM dealership performed the work? Well, it is the grey GM sealant used.

I am not sure what happened in this particular repair, as you see in the photos some of the serts are only partials and this is the main cause for failure.


All in all this was a very bad repair, did I say bad! Because this is ugly in its worse case senario.

The holes in this block are very poorly drilled out and I am trashing it. Yes, you guessed it, it will need to be replaced.

Bummer, now time to tell the owner!





At this time we are behind on all schedules.

However, we are now on full throttle with this SLS

I finished installing the rods and torqued the cap bolts tonight.

I hope to have it in by tomorrow 1 to 2ish afternoon?
