How to fix a timing chain rattle on a 1999 Ford Explorer SOHC 4l V6?

I have one of these and did the whole timing chain - spockets - chains - gaskets etc and cost me more than $2,000 but the problem is now fixed and it is a joy to drive. Fortunatley or unfortunatley bought another with the same engine rattle on startup - but much less noise - the first car had all good looking removed parts that is chains, sprokets, but the mechnic did not give me back the tensioners - my question is can this problem be fixed by simply replacing the tensioners only? This one has half the mileage at only 55,000 km.

And does someone have the procudure for the shortest way to do that by myself?

Can changing the oil viscosity fix this problem?

The last time it was in the garge for 4 months!!!!!!! Hence my fear.

Any and all help appricated.

For those of you interested on my post of not firing on left bank - the exhust values were bent when doing the timing chain swap.

Thanks at least half the responses pointed that out - thorugh a compression test.

Type in %26quot;serious explorations%26quot; - there are TONS of explorer sites. Ford had a redesigned tensioner that threaded into the engine that would usually take care of the rattle if the inside parts were'nt damaged yet.How to fix a timing chain rattle on a 1999 Ford Explorer SOHC 4l V6?
It is a good bet that the tensioners will fix the problem. No oil will not fix it even if you use molassas thickness...How to fix a timing chain rattle on a 1999 Ford Explorer SOHC 4l V6?
Shortest way?



If you are doing BOTH banks, the passenger side chain is best reached with the engine out of the vehicle as it is on the rear of the engine.

This vechile has 4 chains including the one for the oil pump. Engine has to be removed for the rear chain on the right side, and special service tools needed!
