| Noisey Hyd. Lifter |

I seem to be having an intermitant noisy tappet problem on my 69 390 Cougar, it is only the second time it has happened in the 7 months I have owned it.
First time was a few months ago after a long run at a constant 70/80mph it soon went quiet after a slower cruise.
This time though I was only doing around 50mph for around 3 miles and I could hear one tappet quite loud.
I came off the motorway and let it tick over while I sourced the noise and it did not go away, we decied to head home via main roads and within a mile or so it had gone quiet again and stayed quiet.
The oil pressure is ok, according to the factory O/P guage is around 20psi hot @ 550rpm
Temp is slap bang in the middle and I'm using 15/40 mineral oil.
The engine is well maintained and appears to have always had regular oil changes.
I'm thinking a lazy tappet, and may use one of the hydrallic lifter cleaners available.
Is this problem common to the FE's and am I wasting my money trying a cleaner through it.
Thanks in advance |
