Lost oil pressure on my 4104 in Pensacola on the way to Orlando. Bus is parked at the tow company for the weekend. I am in sore need of a referral for a good local 2 stroke DD mechanic for my 671.
Many thanks.

Thanks for the info. Had a head job done on the engine a week ago 'cause the head gasket was leaking compression; now have more power than ever before. But when I pulled the coach over due to low oil pressure, oil was all over the engine from about everywhere it could. It was clean before. A lot from the main seals and out the slobber tubes, even out from the inspection ports (where you can see the pistons). Is this a sign of increased compression blowing oil from a worn engine, or could this be related to the clogged high oil pressure valve theory? Much thanks for your good insight.

Just talked to Brownie and he said they are no longer a detroit dealer and it would be three weeks before he could get to it. Any other referrals would be appreciated.

JT I really don't know of anybody. Did ya ask Brownie if he recommended anyone? If not I'd call him back an do so, as he'd most likely be able to steer ya in the right direction and know who to avoid! |

is it smoking or just leaking ? was it to full of oil ? and was it the right oil 40W only and nondetergent. high pressuure oil regulater working? how much do you gustemated oil loss is. and was it the right head gasket for that engine, they look alike with oil jurnnel holes are different, this is not to scare you but it might be a possability. does the oil pressure come up when you add oil? if not the pump may be bad easy fix it's on the outside of the engine,on the end. hope this helps |

My 4104 threw oil over everything and it was only the connection from the crankcase to the governor loose.
The wire connecting the oil pressure sender could have come loose or been broken during the head job.
Many, many things could cause the symptoms. Could be caused by the same thing or two completely different things. |

Hello JT.
Head job a week ago?
First place to look is the work done and related to that job.
Assuming the original work was done by a reputable party, they will want to be involved in the tear down to investigate.
Only fair, if you intend to ask them to stand behind their work.
happy coaching!

I agree with Buswarrior, if the work had been done in my shop I'd wanna know there was a problem and want to do what I could to see if it was related to our work! |

I am thinking one of the fuel lines inside the head started leaking and overfilled the oil pan, leading to oil blowing out everywhere and a loss in oil pressure.
Short fix is to find/replace the bad fuel line and put new oil and filters. Proper fix is to do the above and install new rod and main bearings. |

Thanks all.
Bus still laid up in Pensacola while I wait for my local mechanic to get back to me. The mechanic in pensacola started it up and it had oil pressure, but after running it for an hour he says that oil started coming out from everywhere, and apparently it was overheating as he could hear "boiling" inside the engine even though the water temperature valve said 180. When it was shut off, antifreeze rushed into the reservoir and overflowed. He thinks its the thermistat and wants to change it, but that was just replaced two weeks ago when the head job was done. He believes the loss in oil pressure and oil coming out from the seals is due to the engine getting too hot and the oil loosing viscosity. The thermistat to which I am referring is on the left of the manifold.
The radiator was rebuilt last year and the temperature guage is relatively new, although the sender is old.
Anyhow, Thanks for your good help and suggestions. I am waiting to hear from the mechanic who did the head job before I proceed any further. He was out on call yesterday and I may hear from him today, although it is a local holiday here and he may have the day off.

Did they take into consideration, that you have 35' up
and 35' back of water carrying lines that support the
front heaters? Not filling to capacity, or not venting the
air blockage from the entire system, can lead to insufficient
coolant capacity... Youse has to run the engine after filling it,
and re-check the level, adding more wa-wa as needed.
But....
Aside from it being from a wrong head gasket, or put
on wrong, I'd feel safe to assume the mechanic is right.
Make sure he puts in Delo 40w cf2. |

Update on my 4104: Pensacola Mechanic said compression was getting into antifreeze. This should have been repaired with my head job just before our trip. Our local mechanic says get it home and they'll fix and spring for the tow job. He said they the block may have been warped and the mechanic on duty may not have checked this at the time. Tow company is getting overweight permits for the three states they will have to cross, so I am cautiously optimistic it will work out.
Thanks all for your good advise and concern.

JT Glad to hear the shop is going to stand behind their work! It makes me feel good to hear I'm not the only honest(translated; "BROKE") shop owner still left! We may not get rich, but atleast we can sleep well(in between calls for a tow/service truck! LOL)! I'm curious about the "overweight permits" thou! I'd think a tandem axle tow truck should be able to leagally scale it unless you have a very "heavy conversion" Also if I was them I sure wouldn't worry about a permit for Alabama! They ain't got no scales on I-10 and I doubt anyone would even notice a tow truck hauling a RV as overweight! But hey it's their butt on the line, but I think they are going a little overboard which is being passed on to your shop! Just my 2cents worth! |
