excessive blowby?
 

hey yall,

i recently got a job at a jiffylube (in college) and got free access to maintain my truck with the shops equipment.

im telling you all this because i noticed excessive blowby building up on my oil cap.
do any of yall guru's think i should start running a full synthetic, or a blend, or continue using 10w 30 like i have for the life of this truck. its a 02' gas 3.7 v6 ram 1500.

IMO stay with what you've been running but check or just replace PCV valve and ensure case breather is clear and clean then monitor results if no change have a leak down test performed this will give an idea of ring condition Changing to syn. may cause increased consumption due to how slippery it is

Toss a can of Restore in it. It will seriously do wonders. Then seafoam the hell outta the truck thru the vacuum line (brake booster)

Oil additives should never be used.

The only thing that can be done about blowby is to rebuild or replace the engine.
If the engine starts and runs fine, there is absolutely no reason to care about how much blowby it has. The only time to care about it is during the vehicle purchase phase.

For a diesel, I would agree with that. But we are talking a gasser; I've used Restore in MANY MANY gassers and it seriously does wonders. Blowby in a gasser is BAD. Blowby in a diesel? Normal.

Makes no difference. An engine is an engine.

Psychologically, yes. Physically, not really.

There is a difference. Diesels are very sensitive to clean oil; ie HEUI units. For a diesel you want the oil perfect to maintain the motor. Saying that "an engine is an engine" and that gassers and diesels are similar is silly.

In the cars I've used Restore in, it's decreased the amount of oil burned and blowby as per the oil cap. Slightly better mileage and an overal more crisp motor are also results.

It's been a while since I used that though.

Only to those that think there is a difference. Pistons, rods, crank, valves, cam, oil pump, etc etc, all the same components. The only significant difference is the combustion system and the soot diesels deposit to the oil.

Thats not really possible outside of marketing. Any particles big enough to do that would get filtered out by the oil filter.

I'm thinking you are confused. Restore is a thick liquid that adheres to the walls of the cylinders and hardens, filling in cracks and knicks. When cracks and knicks are filled in, there is no more (or at least limited) blowby.

There is nothing similar between a gasser and a diesel except for basic parts names (as you mentioned). Thats about it.

Blow by building up on your oil cap? This doesn't make much sense to me? If your refering to the kinda think i think the color is white, stuff building up on your cap it's normal for dodge gassers to do that. i also worked at a Oil place and i noticed that pretty much every cap i pulled off of 1500s durangos and other dodge trucks and suvs had that on it. so if that's what your looking at then i wouldn't worry about it.
