Had a timing belt replaced in my 2000 Accord LX 4 cyl at about 100k miles. Short time after I noticed the engine making a “typewriter” clicking noise when the car was cold. I figured all the valves could not have gone out of adjustment at the same time but I checked them anyway and they were well within tolerance. Didn’t have to adjust one. My mechanic confirmed to me Honda valves rarely need adjusting unless one is really hard on the engine, which I am not.
Now I still get this “typewriter” clicking noise until the car heats up and then it goes away. The Mechanic said it was piston slap and we left it at that. My question is what in the timing belt replacement procedure could have caused this to happen? Has anyone experienced this after replacing a timing belt?
Thanks.
PS It’s not the oil or valves.

If it happened right after the tbelt replacement then there is a good chance either the main timing belt or the balance shaft belt may be loose. Any way you have get an audio clip?
Sounds like some lifter noise to me. Usually taping when it’s cold comes from the thicker oil not pumping up the lifters
College guy….I agreed with you. I thought the reply might go into your area but it didn’t. What made you say tensioner?

If the timing belt was just done and the tensioner was not replaced.
The tensioner may not be operating smooth or theres to much tension.[quote=”bdazsvt03″ post=48687]Sounds like some lifter noise to me. Usually taping when it’s cold comes from the thicker oil not pumping up the lifters[/quote]
It has a solid valve train meaning there are no lifters.
That said, if the timing belt is loose it can cause more valve noise. The belt tension must be set properly. If it’s not then the cam can ‘chunk’ as it turns causing more valve noise. There is no ‘tensioner’, the tension has to be set manually when you replace the belt.
Another thing that comes to mind is the oil. If the oil was changed at the same time make sure the correct oil was used. The poster that I quoted is correct in that if the wrong oil is used it can cause issues with top end noise on start up, not because of lifters but because of a lack of lubrication. I believe that engine should take 5W30 oil.
