Compression Run Down on a NT

[xxShaneOmac]

So bassicly Im going to buy a NT Talon 2.0, But I want to check compression before to know what Im buying.

Drive the car to operation temps, make sure the battery is charged [bassicly drive it the car]
Pull the MPI
Pull the Connecter from the Coil pack.
Remove Spark plugs check for fouled, [what does oil mean? what does black mean? what does white mean?]
Screw in the Compression tester
WOT and turn over the key 4-10 Cranks [Holding the key not releaseing]

Check Compression on all 4 cyn.
If compression can be raised 10+ with a capfull of oil poured directly into the spark plug whole then this means Seals are bad?


Are my statements true? And where I have questions could I get the right answer.

Also want to know the PSI Numbers for a 2.0NT 93Talon ES

Its like 9:1 Pistion's
193? PSI from the Factory
145 - rebuild time.

What would be a decent number were I wouldnt have to worry to much.
140k on the car.

Thanks

Sound like you got it pretty much right. I am ASE certified in Engine performance and I do not "read" spark plugs, its old fashioned in my opinion. If you add oil and see compression increases(some is normal) that is a sign of compression being lost between the cylinder and the piston rings.

I would be greatful to see over 150 psi on this engine(on all four).

Ok Glad my process is pretty soild.

Now just would like a few more opinions on the numbers,
If the car is looking into a Engine rebuild within the next months [ie. low low compression]
Im not going to pay full price to get shafted and need a rebuild / new engine.

It needs built for the first time my friend so you can turn 10k rpms .

But yeah I know what you mean.

Haha.
Ive gone DSM crazy.

Bought a 99 GSX and started upgrading it. But I love the 2g look and I'm going to spend alot of money on the paint rims tint etc.. get the look im going for. 350-400 AWD Full weight weekend car.

Then need a DD. Talon - cheaper then Eclipse [price + insurance] less known, NT - Good gas, - 4g63 - know the engine +1.

Then I Want to get a 1g AWD strip cage and fully build it.

Blah these CARS!
Haha
