Redtop Sr20det (Need Advice)

[Jybfan04]

I purchased a S13 a few weeks ago and finally got around to being able to work on it. The guy I bought the car from told me that it wasn't currently running and that the injectors (stock 370cc) kept flooding the manifold. So today I drain the oil in preparation for when my buddies and I will work on the car. So when I drained the oil there were a few things that I noticed immediately and that was the oil mixxed with gas :eek2:. The mixture was very thin and it appeared that the gas thinned it out very bad. So I still have plans on bolting everything back together and seeing if she will crank over. Are there any suggestions as to what I should do to help with getting that gas out of the bottom end. I know that gas being in the bottom end is bad and can wash your bearings out but I won't to rule out that the motor is screwed based on diagnosis before just jumping to conclusions. Also any suggestions for motor options ie built or swapping another redtop. I am leaning on doing both just so I can get the car running and send the possibly bad motor to the machine shop. Anyway I can diagnosis this car and get to the bottom of things?

If he didn't run it for long it won't be a problem..... Just flush it.....

How do I go about flushing the motor completely of the gas and oil mix? Is there any particular method or way of going about this?

either your inj are sticking or the inj O-Rings are bad remove and replace as required

as far as flushing the engine just change the oil twice
Fill it up run it for a few mins the drain and fill again

oil is too thin for these high milage engines, majority of the times it spins bearings.

not a fan of the gear oil either ended up fucking up my 1,2,4, gear syncros

drained and filled with Mobile 1 cured 1 & 4th but too late for second(gotta granny shift)
