I went to the dealership where I get my maintance work done on my car, to have him set my fans higher due to high temps after oil weight change we were unable to set the fans cause my tuner is locked, can't make any ajustments. I think my high temp problem found me on my way home, I was at a drive-up window and out the blue, without warning, my engine made a couple of loud taps then seized up. Towed my car home removed the cam cover on the right Pass. side to find that the 3rd cyl. cam follower failed plus dropped the valve (rear intake). I don't know what is going on but that is the third one (cam follower) to go out in 550 mi. sense April I haven't been beating on it or anything due to the exhaust restriction between the pipe reduction to go under the control arms and my Cervini side exhaust restricting flow per say Jim Sr. who tuned my car and was only able to get to 489 rwhp. with 12 # boost without blowing/breaking anything, now i'm waiting for the 3" pipe to go under control arms from Hellion Power Systems sense i'm at stock hight. I hope you are still with me i'm doing my best to help ya'll understand.
The first 2 failures I was using Rotella T 15w40 oil, the first on driver side was at 20,380 mi, had dealership do the repairs. the 2nd at approx. 20,460 mi, I replaced all the cam followers on that side myself and had cam polished, at approx. 20,510 mi. I decided to have my oil filter relocated away from the exhaust, I had them replace the 15w40 with 10w30 wight oil. After they replaced the oil with 10w30 I noticed that my temps were higher, normally sense turbo install my coolant temp was 199*-204* in the city, now was 214* in the city, and my oil pressure was lower witch was 10-12# with 15w40, with sensor on turbo oil line, and now with 10w30 it was 6-8# with higher temps, my rpms were low to, idled was at 500 rpm. Now at 20,931 mi. the catastraphy, don't know what to think I crossed all my tees and dotted all my eyes. The follower that gaveway was new, and if you look in the pictures you can see others were failing too, you can see the heat, may or maynot have been my heat issue. But what is the real issue with my engine, I pulled the other cam cover, and not to my surprise there is a failure starting there to, but there is no sign of heat on the others like the passager side. I wounder why on the right pass. side only the rear intake valve cam followers are being damaged, also the 2nd failure on the right pass. side that I repaired was the 4th cyl. rear intake valve hu???
I attached a few pictures of the damage for you to see, and if anyone can help me make sense of what is going on with my heads, or you may know someone who could. I really don't know what to do, replace both heads or try these again? really cain't aford it though, any help would be appreciated.
