My 1995 Odyssey seems to be leaking between the block and the engine
oil cooler and I plan to remove the oil cooler to replace the o-ring. Can anyone tell me the size of the hollow bolt that holds on the oil cooler on? My biggest socket is 27 mm and it's not big enough. Also, is there enough flex in the coolant hoses to move the cooler to get to the o-ring without having to drain the cooling fluid? I want to get this done quickly since I have no garage, it's below zero most nights and there is little shade from trees in Vermont winter. I was hoping to wait until spring, but I'm losing 2 quarts a week. Thanks in advance! Ed |

Some repairs are much easier when you can raise the car six feet, get in there with a giant wrench, and let all the fluids spill into a large pan. Buy the replacement O-ring in advance so they don't try any tricks with sillicone. |

I agree with you about independent shops, but this job is only a half step harder than changing the oil filter. The bolt is only torqued to 56 ft-lbs, so it shouldn't need a giant wrench. I'm hoping that I don't have to drain the coolant, but if I do, it's as good a time as any to change that too. Ed |

Hi folks,
I got a 98 Accord LX 4-door with 83K miles. I bought the car last summer with 77K on it. I recently have been noticing manual tranny problems.. indeed for some time, even before it got cold here in Indiana. The problem is not tranny slipping, since there has never been a case with RPMs going up and the speed remaining the same at the same time. I may describe the problem as a "bony gearbox", somewhat hard shifting or gears somewhat grinding.. This is particularly experienced when upshifting from 1 to 2 *the most* and also from 2 to 3.. I have noticed the problem MOST when upshifting, for it definitely does NOT have any problem when you DOWNSHIFT from 3 to 2. Downshifting from 2 to 1 has been a problem as well even though at speeds of about 10 MPH. Do you think i need new blocker rings? or new gear cones? or what do you think / suggest ?!! Thanks a bunch in advance.. cheers, --Ersin |

Downshifting from 2 to 1 has been a >problem as well even though at speeds of about 10 MPH. Quit trying to shift from 2 to 1 at 10mph - the box is not made for it and frankly I see no need for it. The synchro on 1 is really only there to provide smooth shifts into 1 when the car is stationary or almost. If you really insist on 2-1 while still moving, learn to double clutch. Does it shift 1-2 and 2-3 smoother if you pause briefly in neutral between the two? How is the clutch and its fluid? You might want to change the clutch fluid and make sure it's bled properly of any air - Honda has no scheduled change for this but IMO it *is* important. >Do you think i need new blocker rings? or new gear cones? or what do you >think / suggest ?!! It could be that the synchro rings or cones are a bit worn. Personally I've never had such problems on high mileage Hondas and if they are worn it would indicate possible abuse by the previous owner. It's also possible that the previous owner put the wrong oil in the gearbox - some people think that since Honda used to recommend engine oil for the purpose, it's better to use a synthetic engine oil. This is most definitely not the case and the first thing I'd try in your situation is to replace the oil with Honda MTF.

It shifts smoother if you hold the clutch a while and then engage in the upper gear. Would you think then MTF and clutch fluid replacement is the best thing to do? Looks like you hit the bull's eye! you knew it.. Thank you, --ersin |

In most cars I've driven, 1-2 is often a hit or miss affair - sometimes it's smooth and other times I feel a slight graunch... magnified when cold of course. The 2K Accord we have does not feel as "positive" as the Integra, I assume because the Civic/Integra is more direct with a shaft which goes straight from the gear lever into the gearbox; the Accord's cable system is better than some other similar designs but when I drive my wife's Accord I do get the feeling it doesn't like to be rushed. It's not bad but it's just not as "slick" as the Integra. >Would you think then MTF and clutch fluid replacement is the best thing to >do? Looks like you hit the bull's eye! you knew it.. The MTF change schedule is 90Kmiles(30K severe) so it's near time anyway but DIY or make a point to insist on the genuine Honda MTF - it makes a big difference and even dealers have been known to just fill from the bulk engine oil tank. Take a look at the clutch fluid in the reservoir - it's probably dark and slimey and if not changed you'll be replacing the master and slave cylinders soon. I'd also check the cable linkage under the hood - it's easy to see and get at. Just brush off any dirt and put a little grease on the cable end bearings - I smear just a little moly-grease and then wash it in with a penetrating grease spray, like SuperLube.

Well, on my 91 Accord, I used a 30mm socket. If you don't already
have one, get a 6-point socket so there's less chance of messing up the bolt. There's enough flex in the lines on the Accord to not have to remove them. Oil up the new o-ring and slide the assembly in nice and easy; you can't really see how well it goes in, but if your fingers aren't frozen solid you can feel if anything binds and pulls the gasket off the mark (and you'll end up with a leak again...). The dealer quoted $150 for the job. And it only took me about a half hour (and a $5 gasket) and I'm really slow. |

Joe,
Thanks for the information. Unfortunately, my Odyssey took a turn for the worse last Friday. After driving less than a mile, the engine stopped and would not restart. There were no bad noises and it would crank but not catch. My wife had to walk home (a separate story in itself). I tried what I could on the roadside and then had it towed to the garage. It turns out that the camshaft had snapped at one of the bearing journals so there was no spark and the valve timing was off. I can't say this is due to the leaky oil cooler seal, but it certainly didn't help. The mechanic's recommendation is to put in a 'good' used engine since there was a fair bit of oil sludge buildup in the old engine. I can't complain too much since the old engine went 180,000 miles. I believe your info for the Accord would be the same for the Odyssey since the engine I'm getting is coming from an Accord. Regards, Ed |

Personally I think your trans is fine, but you actually have clutch problems. It sounds like your clutch is not disengaging properly. It could be a mechanical defect or maybe the release mechanism need attention. I had one where the springs of the clutch disk came in contact with the flywheel bolts and created a problem like you describe. -SP |
