Hi,
I have an exhaust leak on my P60. At anything more than idle speed, the engine compartment fills with exhaust. I have attempted to determine the source visually, but I am unable to pinpoint the location. It just seems to come from the back of the engine, but I don't see a specific "exhaust current", just a cloud of smoke. Does anyone have any ideas on locating the source? Any tricks to narrow down the location? Thanks. |

Best thing is to pull it all apart and find the parts which are bad. You may have a blockage at the manifold or one of the rubber hoses may be delinaminated on the inside. What type of exhaust is it, waterlift or standpipe? |

Hello
Does anyone know where I can get a P 60 service manual?

OK, I've done a little more dianostics, and I have found that the engine compartment fills with smoke only when it is in gear for awhile. I can run it at high RPMs in neutral and no smoke at all. I am beginning to suspect something with the transmission (or reverse gear). Is smoking a symptom of too much oil in the transmission box perhaps? I may have overfilled a little recently (I have trouble seeing the rear of the shaft to judge the oil level.) All else seems to work fine (no slippage in forward or reverse). |

Best way to check reverse gear is to take off the cover plate. Mine has 6 bolts. That way you can see the whole gear. Level should be 1 inch below shaft. I judge ours by the round opening the seal fits inside. It's hard to believe the gear would smoke because of overfilling. When you put the engine in gear and increase Rpms the compression gets higher. I would still lean toward an exhaust leak. Can you watch the engine while someone else engages the transmission and increases throttle? If there is that much smoke you should be able to see it start somewhere. Ours has a little exhaust show up at the oil dipstick cap. This only happens at high rpms and I leave the blower going whenever the engine is running to keep a fresher engine room. |

Thanks.
Yes, I have removed the reverse gearbox cover... I just have trouble comparing the oil level with the shaft. Can you clarify what you mean by the "round opening the seal fits into", and where the oil level should be compared to that?
As for your thoughts on the source of the smoke/exhaust, yes, I will have to do more diagnostics... I understand that at idle the motor is not under a load and compression is low, but it seems rather strange that it doesn't leak at all in high RPMs in neutral, but a lot when under load even at lower RPMs... but I guess if the leak needs some pressure to show up, that could make sense. I will do a little more investigation.
Thanks for your suggestions and advice! |

As you look inside the reverse gear there is a round opening the shaft goes through. This is where the oil seals and bearing are. I judge the oil level by the bottom of this opening.

Several times over the years I have run into a problem right where the exhaust manifold junction with the exhaust line narrows up with carbon and restricts the exhaust flow. This is particularly evident when the PCV line between the valve cover plate and the backfire trap are disconected or the oil filler cap has become gunked up. Should be cleaned in gasoline at least once a year. |

Kevin, thank you for the further details on oil level... I will use that as a guage.
Richard, also, thanks for the suggestion. I will check for build-up and clean. |
