1995 Chevrolet Monte Carlo Z34 with 3.4 liter engine. Has significant issue with oil leakage due to manufacturing defect. The engine block contains a hole which was originally intended to utilize a distributor cap. This model does not use a distributor cap. The hole was plugged by GM and is inaccessible for repair without removing both timing chains, the entire top of the engine and cyclinders. I have contacted GM to request assistance with the repairs which have been estimated at $1500- 2000. Their only response is to offer a certificate which could be used toward the purchase of a new GM product. I have spoken with several repair outlets and was informed this is a relatively common problem but the engine in my vehicle makes it much more difficult and costly to repair.

Internal loss of coolant started shortly after purchase. When I determined that it was an abnormal amount, the warranty was done. Car is presently down until I can afford the head gaskets replacement and possibly replacement of a cracked head. Upon state inspection, leaking rear wheel cylinders were discovered on both wheels. Also, both rear struts were determined to be faulty. Whenever it is very cold, the accelerator linkage sticks and I must shift to neutral to stop without sliding. Occasionally the engine has raced at over 3000 RPM for several minutes after the accelerator pedal has been released. The head gasket problem has happened to several other persons I know with the 3.1 engine. Four different mechanics have told me that this is a very common problem with these engines after 30000 miles.
