Here is an update about my engine problem. I decided to do a test run before I decide what to do with my engine. The first opportunity was beginning of May. The engine run good and top speed is 55 km/h. But I noticed white smoke was coming out of the carter ventilation. Also the engine used 2L...
Replacing it is. A new pump is 250-300 dollar, I need 8M0073435.
There are 50 euro Chinese version of this pump. Does anyone have experience with this...
If got the engine finally running, Just the fuel pump is 'overflowing' through the sight tube. So I need to replace this. As a result mixture is too rich and engine is smoking. For the rest engine sounds good, runs even on 4 cylinders.
I ran the engine for a few minutes to warm up and did a...
Happy New Year.
Engine is turning on the starter so I could do I a compression test:
1: 115psi
2: 125 psi
3: 130 psi
4: 90 psi
This is done with a cold engine, so not very reliable, just for indication.
I will replace fuel and oil so I can start the engine and do a proper compression test...
So I took off all rocker arms and now the engine can turn all the way. So a piston was hiting a valve. I added some oil to every valve and place back the rocker arms. Engine can still turn freely, so problems was a stuck valve.
No I have to get the starter to operate, the solenoid is stuck.
What I've read is that the engine will get damaged when overheated, and the original alternator sucks. For the rest, how bad can such and old-fashioned engine be? My engine ran 300 hours, and I will use it 50 hours per year. That is similar to driving 15.000 miles. Shouldn't be a problem....
OK, I will check the valves. I just noticed that valves are moving during this 180 degree free rotating. When a valve is stuck there should be space between the valve and the rocker arm? I didn't noticed that.
I was thinking of this. But what if there is some uneven surface on the cilinders due to standing for years. When I use the force of the starter this could damage the piston ring?
I can remove the cilinderhead in my garage, but replacing piston/engine is a bit too much for me.
Hello, my name is Thomas and since 8 years boat owner again.
I bought a speedboat with 3.7L Mercruiser 1992 that was standing still for 4-5 years, engine has 300 hour and looks in good condition (see picture).
According to the previous owner the engine was doing fine before the it was put in...
Re: Slipping propellor
Well I took out the drive, very easy to do. Especially when the boat is out of the water:)
I tried to look at the engine coupler but I can see much wrong. I took a picture, maybe some of you can see more then I do?
