OVERHEATED now running sluggish

[tekung89]

well i've been having heating problems, and the reason was because my oem radiator was leaking. so one night i gave it a run and the car heated up. i drove the car for 30secs while the water temp stick was at 80% (H = 100%) because i needed to find a place to pull over.i then quickly took my 3Lwater bottled and watered down the radiator (engine was off) and sat around for it to cool.

anyways i drove the car home eventually and the water temp was still at 60%-80%. i started the car the next day and it seems like the car kinda struggles abit while cranking but it does start. car sounds abit louder as well, seems abit weaker wen driving up a hill .

my plans tomrrow are to
change spark plugs ~ heat might've caused them to fail
retorque the head to 70lbs (reason being is wen i took my sparkplugs out the middle two were kind of loose, maybe the head have caused this which makes me thing the head studd bolts have come abit loose so from the previous toque of 60lbs its going to be 70lbs)

~ if it doesnt change then im gona change the headgasket ~_~

When you blow a headgasket from water jackets to cylinder. Water can seep in to your cylinder when motor off. This could explain your problem starting.

As above, you may have blow a headgasket or you may crack or warps the head block when you puring water into radiator when engine still hot.

Umm, I don't think so.

Why drive the car when you know its overheating? Should of tow it... besides that, you should of turn on the heater on full blast to reduce the heat.

My beat is headgasket

sounds like a headgasket to me as well, when you change the spark plugs use a torch and peek down each cylinder. Another way is to give it a good drive, turn off and start the next day, it should be difficult to start.

Best of luck though

My heat problems were my head gasket...

Small leak in the water jacket to cylinder 4

Dang!!

Coursed by overheating in peak hour traffic!!

changed the spark plugs and she cranks and starts fine now (spark plugs were the problem). i dnt think the headgasket gave way yet. the cars still a tad bit louder then before but its in a ok state to drive now. thanks for all ur help

must be the new turbo manifold u have .....

[tekung89]

havnt installed the new manifold yet. however my one is leaking and wen reving at idle u can see smoke come out. its quite bad now and i think that is wats causing my motor to play up abit.

if my cars completely warmed up , should it idle at 730-750? because wen the fan kicks in the idle drops to like 590-600 and the motor struggles for that split second and it jumps back to 730-750. usually it doesnt seem to struggle wen the fan kicks in that much from before the overheat occured

did compression test guys, took my sparkplugs out and check every hole, all three got 180psi or somthing, cant remember how it was measured on the gauge, but one hole got 90psi so im pretty sure its a HG problem. thanks for ur help

Sounds like you need new rings to at only 180

Mine are 200psi
