Last September I got caught in a hurricane, in an effort to save the truck from being swept away I drove through a substantial amount of water, which ended up hydro locking the motor. My insurance company paid for me to get a brand new reman'ed motor from Jasper installed. I have put around 8k miles on the new LQ9. Since, the motor burns about a quart of oil every 2-3k miles. Jasper does have a 3 year/100k mile warranty. I called Jasper, citing the problem as I felt this amount of consumption is not normal or acceptable. They told me that burning a quart of oil every 1250 miles is acceptable and does not warrant a replacement. I am installing a Kenne Bell blower along with all the necessary supporting mods...my question is since Jasper claims this is normal, would the addition of the blower negatively effect the motor even more so? I have seen the recent threads about motor break in, and this motor did see some spirited driving initially, but was not beat on. So I am assuming the rings werent seated properly. Jasper has documneted my issue if more problems arise...should I just install everything and hope for the best? Open to any and all feedback/suggestions.

 

Personally I would take up fight on the motor before modding it. That is not normal consumption IMO.

 

I have talked to two different warranty guys, including a supervisor and they said they aren't going to do anything about it at this point...I have $6k in parts laying around that I would like to put to use...I figure if I install everything and it blows, then I'll remove all aftermarket stuff, return to stock and then have them get me a new motor. Any idea what would cause it to actually burn this much oil? My exhaust tip is BLACK!

 

Valve seals and PCV system. Are you running a standard 5-30 oil in it???

 

I think I do have some PCV or EVAP issues...which will be addressed during the build...truck throws a bunch of EVAP codes right now...Yes I am running Mobil 1 5W-30...

 

Try this.

Remove the PCV and vent the crankcase to the atmosphere with filters on each valve cover..

report back after about 3000 miles.

My LQ4 with 140k miles on it burns about 1 Qt every 3000 miles.
unhooked the PCV, and it doesnt burn enough to even notice in 3000 miles...
Dunno whats up with that, but it makes a difference.

 

10-4. Its probably going to take me a year to put that many miles on it, now that it isn't my DD. So I guess just go ahead with blower install???

 

The oil you run could have an effect on it as well. The synthetic oils tend to get past seals much easier because of the lubricity on the microscopic level. In some cases on the synthetics I have found that going up to the next weight aids in reducing this. Like going from 5-30 to 10-30.

On forced induction motors It almost seems like you have to run a 20-50 because of the heat breaks down the oil.

 

A reman engine is not a brand new engine plain n simple.

Large engine and transmission rebuilders like jasper expect a 40-50% profit on every unit they sell. Very very few parts are replaced, if rings are bad on one cylinder only that cylinder will get new rings. The goal is to reuse as many parts as possible.

 

That may be true in the transmissions but not on the engine. Jasper does actually rebuild the engines. However they may not use the best parts. There not going to buy Pistons and rings from GM there going to get them directly from a piston and ring manufacture and it all depends on were they get the best deal. same with gaskets and seals.

The up side to Jasper is that they cover parts and labor on there warranty. the down side is that you need to have the mechanic make the call and push the issue. If you call in as a consumer there going to push you around. If your a well established shop and you use them you have a little more leway in getting things pushed through.
