1993 Mercury Tracer Repair Question
1993 Mercury Tracer Loud Knocking Noise - Internal Engine
1993 Mercury Tracer 4 cyl Two Wheel Drive Automatic 120K miles
1993 Mercury Tracer 4 Cyl. Engine has approximately 15K miles on a rebuilt engine-No warranty. First thing one morning all of a sudden the engine started making a internal knocking noise. The knocking noise increases as the RPM’s increase. Performance is excellent. The knocking noise has no negative effect on engine performance. It also has a slow water leak. The car was taken to Pep Boys for diagnosis. Their evaluation was: water leak is from a cracked radiator, the knocking noise is coming from the lifters. They can replace the radiator, but they do not repair internal engine problems. They stated that the loud knocking lifter noise is not a major problem and the car can be driven without causing any further damage to the engine. I will have them replace the radiator tomorrow, but it will be another 30 days before I will have the funds to have someone else to fix the lifter noise problem. **My question is, in your professional opinion, do you think that if I drive the car very conservatively 10 to 20 miles a day in big city traffic, trying to avoid exerting any extreme stress on the engine, that it will be OK for about 30 days without causing any further damage. Thanks
Hi chiefgreywolf and welcome to 2carpros
My professional opinion its not advisable and again you might get lucky within 30days driving it conservatively as indicated but if that noise is getting worst/louder you have to stop. There's no valve clearance adjustment its hydraulic valve lash adjuster, when the lash adjuster goes a camshaft is also needed this 2 work together as a team in the valve train.

Hi rasmataz, I didn’t fully understand your answer. I will not be doing this repair myself; I will have to find a mechanic to do the repairs. Actually this is my daughter’s car that lives over a thousand miles away from me and I was just hoping all that needed to be done was taking off the valve cover and adjust it. I do not know anything about Hydraulic valve lash adjuster’s. I donated $10 thru Paypal when I requested an answer to this question and I would like to donate again, but I live off of Disability from Social Security and never have enough money to buy food for the whole month. QUESTION **Are you saying that I will have to replace the Hydraulic valve lash adjuster and also a CAMSHAFT? And is this a major repair that could be expensive. I really appreciate your help and will definitely input a positive feedback. Thank you very much!

Sir-You have hydraulic valve lash adjuster and its not adjustable-fix by replacement the problem here this lifters rides on the camshaft lobes and they do get wear and tear that's why I mentioned camshaft replacement. Pull the valve cover and replace the adjuster don't worry about the camshaft
You don't have to re-donate I will continue to help you but keep me posted what's going on with the repair
