- 2001 ford sport trac
My 2001 4wd sport trac has only 60k kilometers on it, it has the rattle sometimes at start up. Having read so many posts about timing chain problems, plus the engine out and special tools needed to fix cassettes l am in the process of fitting a pre oiler.
I have checked oil pressure at the fake pressure gauge outlet which is 20 psi and at the filter adaptor I made from engineering plastic, which is 22 psi, engine warm at 700 rpm. The oil is 5 - 30 magnum full synthetic.
This occasional rattle scares me as it is an indication that things can only get worse. The rear tensioner is good, but drains of oil when engine is not running, over a period of two days. I have removed spark plug cables and fuel pump relay, cranked the engine until there is slight oil pressure and there is zero rattle on start up, ever. My honest conclusion is that the lack of oil in the tensioner after standing causes fatigue and failure of plastic in timing cassettes.
Hence the immenent fitting of a pre oiler pump.
The next thing to fit, is a centrifugal oil filter, does any one have any experience these, any advise would be greatly appreciated. From researching these on the net it looks as if they will clean the oil down to half a micron particle size. This is way way better than your 20 micron standard oil filter, plus
The oil stays clean from soot etc so it seems.
The setup I envisage is pre oiler pump(40 to 60 psi)at startup, then valve closes off pre oiler and redirects oil pan oil through centifuge oil filter and clean oil sent back to oil pan, which is then pumped by normal engine oil pump around block, the standard oil filter is still in place, on my engineering plastic adaptor. The pre oiler pump has a dual task ie pre oiling through filter adaptor and pumping pan oil at 40 to 60 psi through centrifugal oil filter. This pressure spins the centrifuge up to 6000 rpm, allowing only cleaned oil back into oil pan
Any help, constructive criticism, advise welcomed.
Cetrifuge is on hold.
Well the progress is slow but hopefully sure, I've ordered parts and they are being shipped here as I type (6 September 2015).
The pre oiler is a gear pump from Amarine Made (China product) from Amazon for $78. It is my affordable choice producing 20 to 30 psi. I really do not know if this will work, but spinning the engine with fuel filter relay out and plugs disconnected shows very small pressure on gauge and prevents timing chain rattle. I'm assuming this pump will have a bigger effect on oil pressure.
With this pump I've ordered a remote control and suitable relays for easy on off operation, we'll see.
Other add ons ordered are elctric fan, remote oil filter, large transmission cooler and garden nome for the bonnet (hood)ha ha
More to come in a month or two(all items by sea freight from USA to Philippines).
