When I said that my Engine was cleaner, I was being facetious. The residual Trans. fluid stuck to everywhere will dillute into the oil and be like you put Marvel Mystery Oil in the Crank Case, what is wrong with that? |

I bought a 1979 Dodge Van B-200 with a 360 Motor. I am ashamed to say that I was too busy working on the floor covering business to change my oil and too cheap. The oil built up under the Intake was Paraffin(wax) I believe in the Oil and stuck to the underside. Years later I had to scrape that clogged mess off the bottom of the Intake Manifold. How embarrassing is that today? Secondly, I followed an older man's ways of cleaning his classic car Engine: this is what he did, he put degreeser on the Engine and got it hot and went to the self-car pressure cleaning place to wash his Engine Hot. I was young and did that to my 1979 Dodge van and then I wonder why one of the cyl. had lower compression, cracked the ring or it rotated and lined up with the others, I suspected.

I hate to even repeat this, but I was told by an older Mechanic that you put a cap full of Brake fluid in trans. fluid to swell the seals to stop a leak???? P.S. By the way Trans. fluid flush did "not" cause my rear main seal to leak. FWIW Last edited by TRADERMIKE 2012; 12-28-2023 at 07:20 PM. |

Your thorough in your research I'll give you that and persistent. Keep in mind I did not do this, a Trans. Mechanic did. He ran a Vehicle with ATF for 300,000 miles and it was as clean as the day it came out of the factory. Argue with that and call him a lyer, I am only the messenger of the good news. Would I try this in my car, the answer would be "NO", for 30 min., it does work and I can attest to it. Case and point for those of you who did not read this before in my thread. I used the ATF- treatment on a Ford Van and it cleaned out the Engine that we had just bought and we used it for about a year. When I sold it, the person was driving home and the oil light came on. It turns out that the oil pump needed to be replaced. So, luckily for me that I dushed out the Engine from the start and got a year out of it. Most of what I have read works, it is up to you what method to use, all of them work to some degree. I have not heard of any that hurt an Engine, even Gasoline, scary... |

I agree with this statement! In addition, it is not the oil that cools the Engine, that's the radiators job, notwithstanding that conduction properties from oil to cast metal to coolant fluids occurs. P.S. Mike uses ATF in his Gear Venders Transmission add-on and that is close to a manual Trans. as it gets, explain that one away, plus the manufacture says to use it... Now I know why my ears were ringing, you should have invited me into this disruption...discussion... Last edited by TRADERMIKE 2012; 12-28-2023 at 07:59 PM. |

I am not an Engineer, but the loads on a Trans. are greater than you think, figure a Drag racer going down the Track... As a matter of fact, every HP and amount of Torque that goes through the Motor must than go through the Trans. so, this novice thinks... |

Not to say that you don't know what you're talking about, but I am only claiming to dush out a Motor for 30 min. with ATF, give me a break, it works for God's sake already...Others are doing the same with Naptha, diesel fuel , etc.. and you think I am crazy... |

Since you claim to have changed the Oil periodically over a long time, did the Engine still get dirty inside and what did you do if it needed cleaning and don't tell me it that never got clogged up with black crap, ever. |

Let me know how to vote, please. Open up a filter one inch from the bottom around the circumference of the filter, then remove the guts and look between the pleats, I saw a video the other day on that topic. I can eat off the Engine in my Engine Bay, both inside and out and dushing the Motor with Trans. fluid did not hurt my Engine, stop taking what I said out of context. The problem with my Engine is this: "How many of you have heard that if you build the upper end of the motor only, that the bottom end will fail and vicea- versa. Well, I built the entire upper end and now the bottom end failed. I guess they were correct. Most likely we think the strong top end out powered the weak old ancient lower end. It was a good thing that we remanufactured the Heads at this time, because one Valve had 3 hair line cracks and at least 2 Valve seats were installed for the Exhaust Valves. When we first started my 1967 428 ci HO with a 1966 Tri-power and TH 400 Trans. we found shortly there after while reaching speeds equal to 130 mph, that we were bending push rods x 2. Because we had a worn out 588 cam and a crack in a stud bolt to Rocker. Over the past 10 years we have found and fixed each issue, as they occurred. Now the bottom end was found to have seven of eight pistons in backwards and at least one rod in backwards, some think it was a race thing to do, I think if you're going to reverse Pistons then do them all or not at all. Reversing a Rod is never done or so I have learned. Now I have to build the lower end and you will find me @ The next Thread will be called: 1967 Pontiac 428 ci Block" Build or not to Build", Myself? I would have begun today with this new Thread but I stumbled across this one and found it interesting that it was about me. P.S. This topic was done when it was in my post. Why bring it up in a new post, haven't you realized that people clean their motors the way it works for them, right wrong or indifferent? Like you rudely did to me, please moderator put a stop to this madness, why let it go on any longer? |

He could have used one qt of ATF and it would have done the same thing. JMO |

I have learned that MMO is similar to ATF and are interchangeable to one another for cleaning everything that MMO lists on their label.

A Mechanic told me about Motor- medic product I think, that puts a layer of ash over the worn-out valve seals to stop the blow by, it worked for me at the time, when I had a problem, plus it filled in the scratches in the cylinder walls, if I remember. The point is there are some products that work for specific reasons. No one product fix all, that is why I have to rebuild my motor now. |

The Trans. Mechanic that taught me about putting the Trans. fluid in his Vehicle said that he used it full strength and went 300 k miles . I deduced from that experience that I should be able to run my engine somewhat cleaner by using Trans. fluid full strength for 30 min. only, using a new filter while doing so, it has always worked for me. |

It is ironic that you said that because it just happened to me. I once put a solvent type cleaner in the H2O system and it caused the Hot water heater element to leak in my current 1992 B-250 Van, but you must remember how rotten and used these parts are and certainly cleaning the rust out of metal, there will be a thinner wall left, goes for Aluminum Condenser units to. As my motor goes, I won't discount that cleaning the engine for the second time using Trans. fluid, kerosene, diesel fluid, etc... sped up the process, but it did not cause it. The motor has unknown miles on it and was rebuilt differently from factory specs for race reasons, in my case. In other words, it was going to happen anyway. |

The one thing that I have learned so far is that the combustion process negates the fact that oil can ever be clean or not turn black. Case and point we just replaced my thin new 10-30 oil with 10-40 which is some 4 times thicker, from what I read, don't quote me and within one run it started to get Black, my roommate said: "I would be worried if it didn't". |

I watched a video on the topic of what lifters to soak and there are pros and cons, so I won't give any advice, but I can say that I soak my Johnson Hydraulic Lifters in oil prior to installation. I agree with your statement: " I think I would have stopped at a flush, without running it." And I would add: on the road. I would keep the vehicle in the driveway without a load on it. See this Thread topic where it originated in Tradermike2012 posts, for more info. "TH 400 Pontiac Transmission Build or not to Build Myself?" The very fact that we are debating it makes my Spidey Sense tingle about the subject. |
