Oil leak

[323joey]

I have a 90 honda, it has a oil leak above oil filter, can i some how tighten a bolt to fix it?

You need to do a little more research to pin point the leak. It could be coming from a head gasket, valve cover gasket, distributor,ect..... once pin pointed more it can be explained how to fix.

Why do you need 2 threads?

As said earlier, do a little more troubleshooting. Clean the back of the engine as best you can, then check it after driving. The only things above the oil filter are the valve cover, head gasket, and most likely, the oil pressure switch which is mounted driectly above the oil filter. Either the threads leak or it is leaking through the unit. For the low price, install a new one with some RTV on the threads.

So where is the leak coming from?

As stated above, its most likely the oil pressure switch.

[batever]

Diaphragm in the oil pressure switch fails, letting oil through (causing leak) and also causing false low pressure reading because the diaphragm no longer gets pushed as far with a given oil pressure (because there is a hole in it).

Very very unlikely to be a leak through the threads, as they are in British Standard Pipe thread, which is an interference plumbing thread. If others have had problems with it leaking through the threads (how could you tell?) then go with the RTV on the threads or teflon tape but I seriously don't think it's necessary. Just install it bare, it will seal.

Take the oil filter off, reach up and twist the boot on the sending unit hard to get it off, and pull it off, then simply unscrew (I believe 28mm socket works, you'll need maybe a 3" extension for it as I recall) and replace with a new one from Autozone for like $8.

Done.

Idk where you (the OP) live but in Oceanside there's a mechanic that will check and replace the oil filter with an oil change, if u get an oil change u could ask the mechanic to fix it and usually they will do it for free or maybe a dollar or two. And if it is te Valve Covet Gasket those are like $25 at o'rielly, kragen, auto zone, etc and u DIY easily.
