timing tensioner

[dashhho]

05 4.0L SOHC. On cold start I get a bit of noise from the timing chain, it lasts for maybe 1-2seconds and goes away. If I prime the oil system (gas pedal to floor) before I get no noise. So I believe the tensioner is leaking pressure and is why the noise is on cold start? Anyone have thoughts?

I have Cloyes tensioners in that I installed maybe 60k kms ago.

Here's what google AI says about it.


Ford 4.0L SOHC engine timing chain tensioners are a known weak point, with issues often appearing around
100,000 miles. While some may last longer with meticulous maintenance, many users recommend replacing the external hydraulic tensioners every 70,000 to 80,000 miles as preventative maintenance to avoid the notorious "death rattle".

While I can't say for certain, I imagine the OEM Ford tensioners are probably more likely to hold up better than any after market tensioner. It seems to be a rare event anymore when an aftermarket replacement part at half the price turns out to be better than that of the OEM manufacturer. YMMV.
