Hi Guys I have 3 AU's 1 1999 Fairlane V8, 1 !999 LTD 6, and 1 2000 LTD V8
The 2000 LTD has a light knock mainly noticable at idle and usually after a service. It sounds like a big end knock but is intermitent. It started at around 70,000k's now done 130,000k's but still about the same loudness. I took it to ford they heard it put it up on the hoist got under to listen and it stopped and thats how it is, sometimes it knocks sometimes it doesn't. The 99 V8 has done 105,000k's and if I listen real hard I can imagine that I hear the same knock occasionally. Has anyone else had this problem? This knock does go away after a few thousand k's after servicing. I suggested a different grade of oil but the powers that be tell me they are using the right stuff. |

I was going to say use a different oil.. what oil are they using at the moment?
I find Penrite HPR15 is very very good.. highly recommend the stuff, ford and most service places recommend 5w30 for these engines, I personally think this grade oil is just too thin.. hence the reason for me using PenriteHPR15. |

Even Penrite HPR 30 which is a 20w 60, that was reccomended to me by someone that used to work at the ford plant.

Yeah thanks for that, forgot what grade they told me they used tried to find it on the bills to no avail. but I'll dump this lot and try your suggestion. Couple of times I tipped some STP down it's neck to shut it up.

If its a knocking sound , not a tapping sound , then i was gonna maybe suggest the bottom end bearings might be the culprit/worn. My old cleveland v8 used to do it badly (after thrashing it hard for a few years ), yet it still ran np for years like that until i sold it ... hehehehe. I just used thicker oil in the end and it shut it up alot .

My AU V8 does EXACTLY the same thing .. straight after servicing it knocks and carrys-on for the first thousand K's .. then "seems" to quieten down a bit. If I listen hard at idle I can sometimes (but it's not consistent) hear the knocking when hot; 2 mechanics have also heard it so I'm not going completely mad. Mine has only just started to do it when hot, so I'm just leaving it until it does it more consistently before I attempt diagnosis/rebuild.
If you find a real cause/cure, please advise! ![]() BTW: I got cold/hot oil pressure check to rule out bigend bearings .. hot @idle was about 30psi and at RPM was 65psi .. sounded fine to me? |
