hey 340cuda thats a nice truck you have also looks really clean

 

So currently you are just using break in oil as an additive?

 

correct
i am running rotella T which I believe has 800 ppm of zinc, and a break in oil with has a lot of stuff in it

 

i'll try that stop leak stuff this weekend, and thanks for the comment on the truck

 

67, That's not a bad idea, I already will have tons of break in stuff in the engine for the first run anyway.

 

ya
dont forget to molly lube the cam and lifters when you are ready to start your engine
btw, make sure you have a fire extinguisher near

 

What is going to catch fire?

 

what is all this talk about zinc in the oil? i never heard of it. so am i doing wrong by wanting to put regular 10/30 castrol gtx in my 340?

 

The issue with the zinc is that with the changing of the fuel and the addition of ethanol there is now a problem with the cams and in order to prevent the cam from wiping you need additional zinc in the oil to keep it all moving smoothly, or just use an oil with lots of zinc.

 

with out zinc, the cam and lifters destroy themselves, and that loose metal is sent throughout your engine, scratching your bearings

Commando, just as a percaution. When I broke my engine in, trying to get it started was so hard. I was cranking and cranking, while spraying ether into the carberator. Some of it must have fell onto the valley gasket, and when the carberator backfired, and the fuel line leaked, the whole engine went up
my extinguisher was in my trunk, so thank god, I was able to get to it quick enough
somehow, not even the wires were burned

 

Oh ok, I will make sure I got one handy.

 

very interesting. i never knew that. so whats a good oil i should use? its an after market cam if that matters.... goin through my records the guy who built her was running redline 20/50? i have yet to do the first oil change since buyin the car.any recommendations? i think the motor has like 30 or 40 thousand miles on it.maybe if that.

 

i am running rotella T
whatever oil you buy, make sure it has zinc in it
others i know of are royal purple, brad penn, VR1 racing oil

 

hey yall, when buying engine mounts do i need to find ones that fit the body or the engine?

 

to 340CUDA answer to your question is both and to tdra id use the vr1 or the high milage from valvoline also as it has some of the most zinc like 1600ppm and since you live in a warm state id also use the 20/50 blend , and 67 i would not use rotella in a non diesel engine as it has way to many cleaners in it but if the engine is fairly new you would be ok , when you start using an oil with the cleaners in it like the rotella and even the full synthetic oils you start removing to much (bad word) but sludge and your engine will start to have a lot of leaking issues and even oil going through your valve seals , i would only run that kind of oil for a short time if your wanting to free up some sticky valves or rings , im not telling any one its wrong to use them oils or anyother brand but ive done alot of research on it after i was blowing the full synth: oils right out of my exhaust and have talked with many reps on the matter , but either way all oil is good for the right applications

 

ive been using rotella for i would say, around 500 miles now, engine is completely broken in, running fine, and it is not burning oil
what kind of cleaners does it have in it?
