2.3 oil pressure dos not increase with rpm

[1195]

Does it cool down quickly or slowly when you slow the engine RPM down?
Also check both hoses to see if the spring goes the full length of the hose. It only takes a couple inches with no spring to collapse. Is it blowing out coolant or just running hot?

Like i have mentioned this before i have only had this motor on the track once and only for about 4 laps and it go hot fast and took a while for it to cool down also. and when i raised the hood there was coolant blown out of the radiator.

UPDATE: got the holes plugged and loctite in. Car holds 40-50 psi at warm idle. When accelerating it holds 60 psi. When i give it gas and increase the rpm the oil pressure raises slowly. It just doesnt jump up really fast but it does increase slowly to 60 or higher under warm acceleration. Does this sound right?

[let-r-eat]

Yes. The pressure relief in the pump limits the pressure and bypasses the oil back into the sump. Sounds like you are good to go now.

Thanks alot. What would you guys reccomend setting the ignition timing at. As in the degree using a timing light?

[Dirtman29]

Set it at 36

5.2 rod 34-36...5.7 or longer rod 36-38...as far as overheating, you mentioned you have twin fans, if they are on the engine side of the radiator,they should be pulling from the front and blowing towards the engine...you can test this by hand, or put a piece of paper on the radiator(front grill area) and see if the paper sticks to the radiator

[clint3]

yes it is blowing towards the engine so that should be good. and i had my first race last saturday and had the ignition set at 36 degrees. The car was cutting out in the corners and after the hot laps and heat race i adjusted the float height and fixed the problem of cutting out, but with 3 laps to go my upper radiator hose blew off and i lost all of my water and limped it to the finish. maybe my radiator isnt doing the job? the car slowly climbed up to 190-200 degrees before it blew off.

I would get rid of the electric fan setup and go to a good fan with a shroud.

i have another question, how big of a radiator will fit in my mustang? im looking at getting an all aluminum one. the one i have now is just a stock radiator

[car62]

stock will work, make sure both hoses have springs in them so they cant collapse, also make sure you run an 11/16 restrictor in the thermostat housing

[Dirtman29]

I ran the fox body V8 GT radiators with the plastic tanks, and never had any cooling problems. They were free from my sponsor when I had my mustang. Im currently running those same style radiators in my camaro, temp maintains right at 190.

Be sure to use a minimum of #4 oil line to gauge. #6 is better and will more closely follow actual engine oil pressure.

190-200 is fine I always tried to be around the 215-220 mark with race gas. Not sure I would want to go that high with pump gas just out of paranoid concerns of detonation.

Going back to plugging the cam tower holes. Is this a common thing to do, or could it be a cam bearing clearance problem? I'm having the same issue & my towers are not plugged.
