engine ticking sound upon cold start
(previously posted to wrong section of board)I have a98 VDP with 132,000 miles. I havea ticking sound from the engine upon a cold start up or when the car has been sitting for a few hours. I took my car into the shop for another issue (mysterious disappearing coolant). The mechanic advised me that the ticking could be a fractured tensioner and showed me an oem first generation with crack. He said that it will cost about $800 for him to take off the valve covers and inspect the tensioner and if the tensioner is bad then it will be about $1,200 to fix.
I purchased the car a few years ago with 110, 000 miles. Got a clean bill of health from the sameshop, but different mechanic. Oddly, when I took it in for inspection prior to purchase I asked about the tensioner. The person then said that with so many miles, the tensioner has probably been already replaced. The first mechanic was correct. I took off the covers this weekend. The tensioners are metal with the plastic glides. I did not see any cracks on the base or wearing of the plastic glides.
If it is not the tensioners, what else should I look for. The car runs great and at this point, I do not what topay $800 dollars for the mechanic to tell me that the tensioners are fine. Can it be the programming on the ECM?
Thanks in advance.

RE: engine ticking sound upon cold start
If the top tensioners are Red in colour(you can see them by removing rocker covers) then i would replace the whole set, they will crack and the guides will fail. change them asap.
I just caught mine in time and saved alot of money, rather than the chain going slack and the timing missing a cog..!

RE: engine ticking sound upon cold start
i would start by doing a complete oil change , you will then know you have the correct grade of oil in the car, which is 5w30 , at least here in the UK for the car,
and it wont do any harm,
old/dirty or too thick an oil may take a little time to get up to the top galleries, and could contribute to top end noise...
you have already seen that the newer metal upper tensioners are installed, so i wouldnt worry too much about that side of things, if you have an engine with the top mounted VVT solenoids ( 4ltr cars only ), these can chatter before getting lubricated
injectors are also known to get noisy as the miles pile on....
just a thought
