omg, i totally messed up my car.
i am soo stupid.

can someone tell me what i need to replace cause i royally messed my self up.

i reved my new motor too high cause of my idle issue ( i have been having idle issues) and without noticing it i went too high on the rpms.

its not tuned at all and its boosted.

here is the symptoms.

after i reved it very high the car stalled out. i thought it was just he idle acting up again.

-the engine sound like a lawn motor.
-coolant was being shot out of the reservouir. so the radiator and engine went empty by the time i limped home.
-the top radiator hose is much hotter then the bottom hose.
-the car wont stay on unless i keep my foot on the gas pedal.

someone told me it might be a blown head gasket.
or
the thermostat is also gone, but i asked for a new one to be installed by the shop so im not sure if it was or not. so i wont rule out the thermostat is gone.
but the temp was fine right before i reved it down the road.

nothing else that is differnt to my untrained eye that i noticed.


how do i know if its just the gasket or could it be a bad piston now? or valve?
the piston is cp forged pistions and the rods are eagle rods.
supertech valve.

gj better hope it's just a head gasket


why would you even do something like that?


" reved my new motor too high cause of my idle issue ( i have been having idle issues) and without noticing it i went too high on the rpms." for some reason I don't believe you

 

check the oil. if it's milky then its mixing with anti freeze. if it sounds like a mower though chances are you damaged the internals.

 

yes i admit i was very stupid.

i gas it cause the idle keeps droping very low and stalls out. so before it goes down that low ill pump the gas but today i did it way to much.

my idle is an issue i have been trying to resolve.

if it is mixing with the coolant what does that mean?

mostly means that your head gasket is gone, and the coolant is mixing with your oil(which is bad)

and to solve your idling issues, have you tried to adjust your idling screw?

 

what does it specifically mean if the coolant is shooting out of the reserviour?

i have a whole other thread on my idle issue.

i have tried almost eveything everyone has told me to do .

do you think the piston is fried? or the piston rings?

the lawn mower sound isnt completely that loud as it was before. but its kinda there.

 

mabey its not that bad (the lawnmower sound)have you checked for a blown exhaust gasket.

 

probably some broken/bent valves

 

If you have a stock rev limit, or at least very near stock, your internals should be fine and your pistons and valves likely kept their distances. If you dont have a rev limiter on an ebay chip, or for some reason its removed... live and learn.

I see this being a headgasket problem too. Look under your oil cap, or better yet, under the entire valve cover. if you see anyhting that resembles light chocolate milk, then you've got a bad blown headgasket and you shouldn't drive the car. The lubricating properties of oil are diminished considerably upon being mixed with coolant and/or water.

 

with bent or broken valves, what would i feel?
or hear?


can you please explain more how a head gasket works?
i dont understand how the head gasket allows or keeps coolant out of certain areas?

also why was the coolant shooting out of the reservouir and why was it not staying in the radiator or engine?

 

if it's squirting out the reservoir then there's probably a blockage(i.e. thermostat). to check on this just take out the thermostat and see if it's still doing this. another reason why this is happening is that the fluid might be getting really hot and the only way out for it to vent is out your reservoir. the head gasket is what it is, a gasket. since your head and block are two pieces you need something in the middle to help separate all the fluids(in laments term) . so if the head gasket is bad, it's not doing it's job in separating the fluids.

 

thanks for the explaination. i didnt know that coolant doesnt flow into the head.

i have seen many people run with out a thermostat in my area.

would that be ok to do as well?
could i just take it out?

 

no coolant does run into the head, it's just that the gasket keeps everything separate(oil stays with oil, coolant stays with coolant). if you didn't have the gasket there would be a little void that the coolant and oil could mix(which is bad). and yeah, you can run with out a thermostat, wouldn't do it for long unless you live in south cali, or arizona area.

 

actually im in socal. its usually 70-80 degrees. the variant in temp doesnt happen very often.

i just did a quick inspection. i wont have time or space till next week or so.

took the dipstick out, the oil seemed ok.
but when i took the oil cap off, it had a milky residue stuck on top.
i am going to assume that there is coolant in with the oil now.
is the damage instant or does it need more running time to have damaged the other components?

the timing belt looks worn on the side.
not sure if that meant anything.

i forgot to list all the new stuff.
new:
ngk spark plugs.
ngk plug wires
thermostat, thats if the shop really did install it.
water pump.
oil pump.
bottom and top all the gaskets and any O-rings.
timing belt.
regrind cam shaft.
cam gear, unorthodox.
cp piston
eagle rods.
supertech valves,
sping,
retainers.
ARP head bolts.

edit:
did also get RACE bearings too.
milled, decked, honed, balance, resurfaced.

sleeved it too.

do you have a block guard?

if you don't ...and it's not the headgasket....you're screwed

you know what i see happening here. that the shop didn't check to make sure that when they took your engine apart that they didn't warp your head. plus they probably didn't deck/mill/plane/resurface your head and block just in case it was warped. and from getting your list, i can now probably guess were the lawn mower sound is probably coming from, you might have thrown a bearing(cause your list doesn't have that). and don't drive with a bad head gasket(which is the cause of the milky oil from under the oil cap). it's probably another cause of your bad bearing(or vise versa). you're going to have to let is sit. unless you want all those good parts go to waste.

 

oops forgot to mention i got RACE bearings.
they are new.

the shop did also resurface, hone, balance, deck, mill, and sleeved the engine.

not sure if that help me any.

hmmm........ then it's weird then? what kind of head gasket? how much boost you pushing? what kind of fuel management are you running? lighten flywheel?


if your lucky then you just might have overboosted it a little and just blew your head gasket. the lawnmower sound has me worried a little. what's your rev limit at? you might have bent valves, but you won't know until you get a compression test done. what octane gas where you using? hoping it was at least 91, and you should have had it tuned also.

 

what usually causes the lawnmower sound?
i am preping up to get the car to be worked on tomorrow.

the head gasket i think was from honda. it looks silver if that helps any.

ill have to order a new one from them unless you guys think another maker is better for this application.

the lawnmower isnt as that loud but i dont remember exactly as how loud it is unless i start it up again. but i assume that is not a very good idea right now.

 

if you have the lawnmower sound it's ether going to be some top end damage or bottom damage. hopefully it's just a bent/broken valve.

 

Make sure your mechanical timing is still okay? May have slipped the belt.

The more you drive it the more damage you will do. You'll need to pull the head to make sure you haven't damaged anything.

 

My guess for the lawnmower sound is a bad exhaust gasket or an improperly tightened exhaust clamp. When you revved it up, you probably blew out the fresh gasket that they installed with your exhaust, or you shook a clamp loose.

 

woah you got grands into this motor, you could have learned about the stuff first, and then went with all the parts. sounds like your messed up bad, thats my suggestion.

 

Yeah you did drop alot of money into your motor, but since you have milky residue under your oil cap you most likely do have a blown head gasket. A compression test will will tell you whats going on. as for the lawn mower sound I cant imagine what kind of sound that is but a bad head gasket can make your car run crappy. If thats what you mean.
