where I have a small bilge pump. I cannot get a hand bilge pump in there and even my small vacuum doesn't get it all. Any suggestions? I have an oil leak
on the port engine and still trying to determine where it is coming from - It is not the crosover oil line, not the filter or pressure sensor...thinkig it might be the main seal now.
There are oil absorption mats that you could stick in the sump to suck water / oil up. Leave one there and change it occasionally.
The oil leak I had in my 2GM20
SD came out of the crank handle shaft. That is an extension of the camshaft. It was very easy to change. I looked at the parts
catalogue when I bought the seal and it was obvious how to change it. Take the pressed steel
housing off first retained by 2 set screws, and as I remember there is a through bolt securing the dog clutch gear
that engages the handle. Take out the bolt and remove the dog gear
whatever it's called. Then you can easily prise the old seal out with a couple of small screwdrivers. Note which way around it is and put the new seal in the same way around. Reassemble. It was quite cheap
maybe $10 but I can't remember exactly. It took less than 15 minutes to do, and now I could do it in 5 mins.
You mention the crossover oil line. It runs from the air intake side of the motor
, then behind the block and up to the cylinder head
carrying oil to the valve gear. It runs under the rear anode in the cylinder head
so that when you change the anode salt water
inevitably runs over the painted steel
oil line eventually corroding it.
I have replaced mine as it was corroded but didn't leak. Now I spray it with lanoline occasionally and attend to it after changing the anode. If that were leaking I think the oil would spray out as its under pressure.
