idk about the pump, but the hoses or radiator are all good. jst got a radiator not too long ago cuz the old one had two nasty wholes in it........the weird thing is the the valve cover has foam build up... there is also some water in the oil

are you sure that your headgasket is good...
to be honest with you. i have no clue. the engine started loosing power within a few months after building it. my compression was 220 which is still good, i just wanted to through some better rings in it because i was burning oil the supplied rings with the pistons i got were trash.
long story short i was running 82mm npr pistons which from what i was told were the best cast oem piston i could get. appartently either i detonated like crazy or they were shitty pistons. im running towards both, because i have heard of others having similar problems with these and they later fixed the problem by moving the top ringland down.
i now have rs machine 82mm pistons on their way and i have cp rings.
im hoping the engine will be stronger, because i had these problems since i built the engine and i was running 100mph traps in the quarter,
that sounds like a head gasket unless your block is cracked which is worst
I'll probably bring it in tomorrow with the $20 bucks Duma is giving me for the bumper lights.
I got the car exactly the way it is for $400 so im not trippin too hard.
my brother inlaw said that the head might be warped a lil.
if the block is craked them i'm Fd!

nah you can pick up a block for a good price usually. same with if your head is warped, you can easily pick one up for cheap. not many people want ls's anymore...
I hope you put another NEW head gasket on when you put the head back on the block!!
If your head is not badly warped you can easily get a machine shop to resurface it for you for a decent price.
So i am going against what everyone has told me, as i do my 94 LS swap in my 90 RS. I am using the injectors and manifold from the LS, its quite simple actually theory and operation over rule experience anyday. The LS injectors will work with the system as long as the resistor box is taken out of the equation. The specification for the LS injectors is 10-13 ohms. The specification for the RS injectors is 1.5-2.5 ohms, +the resistance of the resistor box. My resistor box has a resistance of roughly 6ohms. So the total for the RS injector system is 9 ohms.
The LS injector will get that same amount of voltage wired to the RS obdo harness as it did in the LS harness. The injector is a ground side switch from the PCM(ECU). Only thing the PCM does is command it on by making a ground connection. You can always give an injector less current as long as it is enough to command the injector on, you never want to give it to much, though as it will fry.
This is what i researched in my Automotive Electrical class today. lol

cleaned the head gasked, checked it very close, flipped it over and checked it again. also checked the head and block. spent like an hour looking at those 3. no i didnt put a new headgasket, i'm not gonna drive the car for a few days so its good. (how much is for a new one anyway?)
