REPLACED HEAD DUE TO WORN TIMING BELT AND BROKE BALANCE BELT.. BENT VALVES CAR STARTS WON'T IDLE
1992 Plymouth Laser • 78,000 miles
Car has a 2.0 dual overhead cam turbo engine.Had to replace head due to bent valves caused by we assume the balance belt breaking and worn timing belt.We put on the new head,balance belt, and timing belt. We lined up all timing marks.Now the car will start but will not idle at all the only it will run is by holding down gas pedal. The boost gauge on the tach is reading -7, also there is a loud whistling noise from the turbo. We have re-checked timing,the turbo(all components look good,and seem to be in good working order)Have double checked for any loose vaccum hoses or wires none found. Also have checked fuel pump it is working.Please Help!Have spent over $600 on head, gaskets,and belts and still can't get it to run!
Use some carb and choke cleaner to check for vacuum leaks. Also, did you properly torque the head, intake, and exhaust? To the proper torque value and in the proper order? Did you use new head bolts or old ones? Check compression. You want at least 100PSI, with no more than a 15 PSI variance from high to low.
Used torque&order specs in book.New bolts.Compression is 150.Getting carb cleaner tomorrow.Thanks, any other suggestions.
Make sure the electrical/vacuum connections to the turbo wastegate are properly connected and not leaking.Make sure the exhaust connections are tight and leak free in and out of the turbo. Boost is negative seven, or seven? Negative 7 is a vacuum, which is completely wrong.
