leak down test shows #1 3% #2 3% #3 4% and #4 3% if it were leaking through the headgasket, it would show it on the leakdown test, it would force air through the h/g into the coolant and id see bubbles, the cylinders arnt leaking, im going to do a compression test tommorow to verify.

Are you confused about what you're doing or what you've done? :P

rexsk8er

no, i put in a tempature sending unit from another motor. but i also ordered one ($10) in the off chance that its bad to. Im about to pick up the new one now.

well the brand new one didnt do anything either, wich is kind of what i expected. anyways im going to compression test it today. hopefully that will show the same results as the leakdown test. anyways, im kind of hopeing it is a blown headgasket and hopeing it isnt. i would like to put new headstuds and a new headgasket, but i would rather it just work as is.


anyways i appreciate everyones help.

Just did a compression test. The biggest variation was 10 psi, betwen #2 and #3. That accounts for a 4.6% difference. This motor probly has 2000 miles on it. Its barily broke in, and obviously there is not a blown headgasket. I'm 100% sure its the radiator. It should be here wednesday. Thanks for everyones help


#1 223 psi
#2 225 psi
#3 215 psi
#4 223 psi

I had the same overheating problem as you. Try water and water wetter only(no coolant), get a Jackson Racing 160 degree thermostat and run the fan constantly. Worked for me.

rexsk8er

well, i already ordered a dual core del sol radiator.


im going to get a 160 degree thermostat as well.



one question, are all d series thermostats the same? im pritty sure they are, but id like a definate yes or no. thanks

WOOOOHOOOOOO i got the radiator installed, and put the gutted themostat in it and now it ------ runs like a champ!!! its so badass, anyways im just boost happy now,

doesnt go above 1/2 way

weeee

congrats, glad to hear that fixed it for ya. i wouldn't go with the gutted t-stat though just imo, if its cold outside and you get hot coolant to the block b4 it warms up theres the possibility of cracking it. i'd just use a low-temp like 130 degree thermo imo.

rexsk8er

well i havnt found one for the d16a1s yet.


i ran probly 3 months with out one and it didnt hurt a thing. i hear alot of things about no thermostat being bad, but i havnt realy seen any concequences. hopefully it wont hurt anything, but if i find a good low temp one i will definatly use it
