blow by issues

[type-m]

Looking for a Rb25 cheaper then what I can find online, I found one that someone is selling privatly but it has blow by issues and a blown piston ring, im new to the imports and boosted engines, so im just wondering if its worth buying and fixing up, or is the engine complealy garbage?

well look at it this way. More money usually equals better quality. its a simple "you get what you pay for" situation. If you want something cheap, buy it expecting to do a rebuild. If you have one checked out for compression and everything and pay a bit extra for it then you know its good then you know it wont need a full out rebuild.

I went cheap on my first skyline and it was just headache after headache. this time i took the time to find a stock one, have it checked out and iv had only a couple minor issues. i say save up a bit more and find a decent motor that checks out.

"Buy cheap, you pay dear".

You'll probably find out that it has a hole in side of piston / taken out rings lands (common failure on RB25DET pistons due to knock / lack of a good ECU tune), also scored the bore which probably would result in a rebore of all cylinders (or that cylinder and a thin sleeve fitted, new stock piston, piston rings), fitting 0.5 or 1.0 oversize forged pistons. Machining, etc cost's will start to rise quickly. Best to save and find a good quality stock engine. Or find a Nissan RB30 bottomend from R31 Skyline or VL? Commodore (rebuild it) to replace the RB25DET bottomend which should give you more power, torque throughout powerband.

Planning on doing a big build? If so this would probably be perfect cause you will more than likely get it dirt cheap. Just hope that it's just your rings and no serious damage to the side of the cylinder (less likely) but if you just want a car to drive then don't bother I would say.
