Im experiencing a piston slap during cold start. Is it normal for this car ???

 

Welcome to the forums.

I moved this to the 2nd Generatrion TL Forum since you indicate you have a 2000 TL.

 

Thanks

 

Does anyone here have any suggestions ???

 

Piston slap is not normal on these cars. Are you sure its that? I have only seen 1, maybe 2 possible cases of it in all my years here.

 

Well I have done most of the test that one can possibly come up with. But it becomes very obvious when I pulled the coil off the plug while car was cold the noise have faded instantly. But what bothers me the most that the noise is only there when there is a load. I mean when I engage drive or reverse. It is happening on 2 cylinders. The car just hit a 100000 mile mark and I have always been using premium gas and synthetic oil. Also the valves were adjusted by dealer less than 6 months ago. If you or anyone have any common suggestions please share them with me.

 

If it is infact that there isnt any thing you can do other than a tear down or replace the motor. Since you have had some work done on it your only recourse is to live with it or pick up a used low mileage motor and stick it in (they can be found for 5-800 bucks now) These motors are very strong and that isnt typical.

 

Thank you for your answers. I kind of figured that this is what will have to take place but needed a second opinion.

 

Unless the noise really bothers you, I'd do nothing. Although rare on honda v6 engines, it's not uncommon on high mileage honda 4 cylinders. I've seen many go well over 100k miles more after the noise started. On the ones I've owned, I let them warm up a few minutes or drove easy for the first few miles. The only one I ever tore down still had cross-hatching on the cylinders, and the aftermarket pistons measured SMALLER than the ones I took out. I put it back together with the old parts and lived with the slap.

 

I love the car a lots but I hate the sound. Im going to pull the motor and look inside for something abnormal. I have checked the oil pressure which looks great and the compresion checked 175 on all cylinders. I just want the car to be quiet in the mornings again.
The diesel kocking just makes the car sound like a junk.
