So I (think) I found the issue a few weeks ago.
One of the spark plugs ceramic was cracked causing a spark grounding to the block — so zero ignition in that cylinder. I believe the unburnt fuel from that contaminated the oil, reducing its viscosity and thus pressure. Also, explains why the oil...
Thanks for the response. I had a cylinder misfire (plug porcelain was cracked, arcing to the block, so zero ignition) that (I believe) caused the oil to get contaminated with the unburnt fuel, and causing low oil pressure once warmed up.
I used the pump that threads on the dip stick but only...
Quick question, the hand pump that threads on the oil dip stick, does this actually remove all the oil in the pan? If not -- how much remains?
Also, can anyone link me to the brass adapter I can thread on the "easy oil change tube" coming off the oil pan so it can be connected to a pump?
Thanks for the responses folks. If this occurs again, and I verify that there is no drop in fuel pressure when it occurs, what would you guess is next to verify?
I already replaced the TPS early this season because the engine kept surging. What else could it be -- MAP sensor? The TPS was...
So just so I understand correctly, when you poured out the contents, you didn’t find anything unusual. It was only when you attempted to clean the filter with carb cleaner that you discovered the sediment it ended up holding — correct?
Thanks for the reply.
I don’t think this is too off topic at all.
I was considering replacing my picking and anti-siphon anyway.
Here is what my pickup looks like. I assume they welded the threads to the tank so I don’t have to worry about unscrewing that while doing the pickup?
Thoughts?
I will check the fluid level, it could be low.
What are your thoughts on the problem no longer presenting itself? Could it really be the fuel filter/water separator was clogged?
I am going to fill the boat up with fresh fuel and run her again for a while to see if it presents itself again, but...
So I very briefly took the boat out today as it was very choppy and windy.
Firstly, removing the vacuum line did increase the pressure by about 5PSI.
During idle and underway fuel PSI was about 24-25PSI. Getting on plane and cruising was 30PSI — which I think is good because the regulator is...
Thanks for the reply.
No secondary fuel filter or low pressure fuel pump.
The cool fuel module is hard to get to without removing the port manifold and elbow. Rather than remove the vacuum line, would briefly pinching the return fuel line and watching the fuel pressure also be a way to verify...
