Flash's new truck is staying in the man cave for a few weeks. I noticed yesterday that it had marked it's territory VERY BADLY. We are all used to our old cars leaving a mark but this was beyond the usual; Attachments:

I was lucky, because the freshly painted engine had been mint and clean before it did a black wee. At first glance, it seemed to be coming from the oil pump / scavenger pipe area. Attachments:

So I cleaned everything down and started the engine, and upon inspection it soon became clear where the source of the problem lay. It was the oil filter mounting plate, and oil was really pouring out. Time to investigate. I carefully removed the spin on oil filter fitted by a previous owner. It was Really tight, I had to use a filter wrench but even then it was tough. This aroused my suspicion as to a possible cause. More on this later. |

The purpose of the plate is to allow oil back into the engine only from the top of the filter, thus trapping all heavy particles, swarf, co rods etc I took off the plate ( which had clearly been fitted upside down)

Whoops sorry guys, the plate is fitted with some holes at one point, in order to only allow oil from the top of the filter back in to the motor, in theory trapping heavy particles in the filter. This had been clearly fitted upside down and was allowing oil from the bottom of the filter straight back in the engine. (So a good thing out of a bad one to spot this at an early stage) I took everything apart, cleaned the gasket for re-use (emergency repair, remember, so no replacement parts ordered!) and generally cleaned all surfaces. Applied a thin coating of gasket compound on either side of the cleaned up rubber seal and replaced the plate, which is held on by the double threaded boss which also holds the filter. Then I cleaned the filter o ring and wiped it with a little oil. Refitted the oil filter hand tight and ran up the motor. Lo and behold, five minutes running without issue. It's now as dry as a bone, no leakage or weeping visible at all now. My theory is the over tightening of the oil filter has led to the plate being slightly bowed out, resulting in oil being able to squeeze past the seal. Hopefully now Flash will be able to go to Leeds cruise on Saturday and not leave truck DNA everywhere he has been! The right hand rocker is still misting a little, but I'm sure a baffle inside the cover would fix that. Attachments:

There you go,my first and only build thread (because I never usually have my phone in the garage, it was only because I was showing Mark what I found that I took any pics!)

If you can build all of them this quick, you'll be turning loads out once the cave is finished....  |
