Well I live in Cali and temp were pretty hot today. My temp showed around 200-215 F throughtout the day. Anyways i parked for half hour and car hesitated to start..like it always does on hto days. But ocne started worked fine. Then one block from my house when i was on throttle...not too hard i heard a pop. Not a loud pop though. First corner i turned engine lsot a little power then when i turned into my driveway car stalled. Now won't start blown engine? Or some ehat related issue? Thanx in advance

 

Remove the spark plug wires. Pull the front bottom spark plug and have someone crank it over. Look and listen for even compression pulses. Then replace it and do the same with the rear. How many miles on your engine?

 

Apex seal or coolant seal ?? Hard to tell ... listen to the bumps , and do a compression check 1st ... good luck

 

Well I have 88k on it but rebuild was done around 70k. But it was done at R&R rotary :\ K if I do compression check and the pulse soudns equal then what could it be?

 

what did you guys mean by listening to the bumps sorry i'm a newbie.

 

you want to hear pulses of air whooshing out of the spark plug holes, indicating that the rotor face still has compression. You should hear 1/revolution for one rotor or 2/revolution for 2 rotors.

 

It could be many things like bad coil, short in the harness, crank angle sensor problem, ignition wires, spark plugs fouled. How much boost are you running and what are all of your mods? Were you at full boost when this happened?

Take out one trailing or top plug and crank the engine over while it's out. Basically you'll hear noise. If all of the sounds don't sound the same there's a problem. Then put that spark plug back and take out the trailing in the other housing and repeat. you should hear 3 pulses on each housing in a pattern you'll see when you try it. Have someone crank and stand by the driver fender it's pretty loud.

 

Did your check engine light ever come on? and/or is it on if you start the car again?

 

It makes no since to speculate on something else if the engine has no compression. Do the compression check first before doing anything else. Like we said earlier, just pull the plug and listen. Then get back to us with the results. Diagnose one problem at a time.
