So my gsr trans took a crap on me the other week, and i happened to have a spare b16 tranny in my garage. I replaced transmission and took it for a test drive. Dropped the car to 3rd. and did a pull, went to switch into 4th. and the car caught 2nd. at about 80 mph. Immediantly the car had a completely different exhaust tone. I pulled over and it sounded like the car was almost camming and the motor is shaking real bad at idle. Only when it idles does it have a miss and the motor shakes, but the car still drives fine and still pulls hard. Im thinking I maybe shocked the motor and maybe knocked it out of timing any suggestions|?

Also put new spark plugs and wires in and changed the oil right after it happened there was no metal in the oil, but the oil is really thin and soupy but still has dark color and i havent lost any antifreeze. Anyone have suggestions for that problem too would be greatly appricated.

My guess is you bent a valve. Do a compression test. If it does have a bent valve try not to drive it before it gets fixed. The valve head my break off causing excessive damage to the engine.

but if i had a bent valve would the motor still pull hard? I dont hear any knocking or ticking

It is just (as we call it) tipped. It will bleed off compression at low RPM but engine RPM hide the problem up top. Since it is just tipped it bleeds pressure off slowly. DO THE COMPRESSION TEST. If you have access to a cyl leak down tester, thats even better. A vacume guage attached to the intake is a way to check if it is intake valves that are bent. I can go on, but there is no reason. Just check compression and get back to us.

ill do that, thanks for the help, wat kind of numbers should i be looking for?

QUICKVIII

Compressions depend on modifications, but 200 psi up. The thing to look for is the difference between the highest cyl and the lowest cyl. If I'm right though, you will have a big difference. Also make sure you disable the ignition system and also hold the throttle open when you do the test.
