![]() Looked through all my notes and found the suppliers I used for Main and Flywheel bolts.įoray group who will try and source bolts throughout Europe.īurtons who do race engines but I got big end bolts from them. Might be of some interest.īest of luck with your engine and let us know what you find. I have also posted a link to all the other Ford XLD problems I have encountered. I had a nightmare of a job finding the ones for the 416 engine as the following link will show. Out of interest, were you able to find a source of Torque to Yield bolts for the main, big end and flywheel bolts. I am sure the blanking plate is available from Lancing. I did however leave a shortened piston in place to prevent loss of oil pressure. I actually removed the vacuum pump on my engine by making a blanking plate and a drain line to the sump. This is a “clutching at straws” solution because I would have thought that the actuall displacement of the vacuum pump working as a compressor would be easily vented through the breather. Is it possible that there is some problem with the vacuum pump internals and it is actually pressurising the sump. You will notice that there is a pipe from the vacuum pump going down into the sump via the dipstick tube which is the oil drain from the vacuum pump piston which itself, is driven from the camshaft. The 1.6 and 1.8 have the same vacuum pump. My other thought would be the vacuum pump mounted at the rear end of the engine mentioned in the various postings. Are you 100% sure this item is working and relieving crankcase pressure. Looking at my Ford Technicians Product Training manual for the 1.8 this would seem to have the exact same plumbing as the 1.6 albeit with the breather in a different place. This breather valve is the only exit for excessive gases on these engines that I can see. Going back to your engine, my first thought was the exact same as Duncan’s as the 416 has a breather valve mounted on the side of the rocker cover (I know there are no rockers on an OHC engine but don’t know what else to call it) I ended up rebuilding my entire engine including a rebore, new pistons etc. ![]() I had quite a bit of blow back through the rocker box oil filler but did not have a problem with the sump being emptied but then, I did not have a sump pump. I have 416 (Ford 1600D) engine in my boat which has suffered from just about every ailment known to man but not had this one. ![]()
