Well, this was a pain in the arse. I started at 4pm hoping it would take about 2 hours...finished at 10pm (ok, 1 trip to the hardware store for some washers....ate dinner). Using the open end wrench to put the top seal on was easy...but the angle didn't work for the bottom..that one took about 30 minutes to get in there and finally used a hack saw blade with grease. And getting to that blind nut...what a pain!
Anyhow..it's all back together and I couldn't find any info on tightening specs in the factory manuals...so the blind nut (I assume this is just to keep the cooler stationary) I tightened up tight using a tiny wratchet...and the two nuts over the seals i tightened with a small wrench just till I felt hard resistence using one finger to push the wrench up with. Was that good enough? Hopefully I leak less now. The new seals didn't look exactly like the old ones. The ones in there seemed to have a larger edge on one side versus the other. The new ones looked the same on both sides. Anyhow...how tight should those seal nuts be? |

The oil pressure switch can be hard to detect. Sometimes it just seeps oil. I would recommend using some brake cleaner to clean up the sender and the area around it that you can see through the sheet metal, then go back and check it later to see if it is no longer clean.
The other thing on the front of the engine that can leak is the oil galley plugs as they loosen with age. There is one that is just above the oil filter that I lost on a very cold morning when my oil pressure was up. In hindsight I should have known that this is where my oil loss was coming from, but at the time it wasn't obvious to me. It's very dangerous if you blow out an oil galley plug - especially if you ignore the green light and drive it because you are sure you've got oil! (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) Wanna guess how I know that? The ultimate solution for a loose oil galley plug is to have them removed, tapped, and plugged with threaded plugs. This is normally done when the engine is being overhauled so that you don't have to worry about metal shavings, but in a pinch it's been done very carefully with the engine still together (but not by me). |
