This is a post that I sent to a different forum.

Well I just finished my first oil change with my new used perf. condition 1991 Prelude Si with AWS. The thing is I messed it up all at the same time by stripping either the nut that goes into the oil pan or even worse the oil pan itself. What I was wanting to know from you guys is how much will a repair be if it can be repaired or how much a new oil pan is. I really do hope that the oil pan can be fixed or that it is just the nut but from my bad experience from things stripping that it is usually not the nut but the thing the nut is screwing into. Thanks for any and all of the help!

BTW: This is my first post ever and I just got my Prelude 3 weeks ago and I am very pleased with the car accept for the fact that mine is stock and has no pick up at all. Grand AMs blow me away. But at least the motor is in perf. condition same for the transmission

P.S. Do you know where online I could order an Oil Pan?

I don't think it's too expensive to remvoe it. There's a certain procedure to remove it and I can't remember exactly how it works.

I do know one thing I have seen those cars in action, they are something else.

An oil pan is an easy part to replace, just a few bolts and some oil stains and it will be easy, as for the part itself try ebay...im sure its there, or advanced auto parts might have it, it shouldnt be too different for most 4 cylinder engines...

yeah it looks very easy to remove and install but you kind of have to remove the exhaust as well.

I love this car though. It is in perf. condition like no rust no mechanical problems no weird noises! great on gas runs like a dream looks sporty and different, can do a U-Turn on a country road (you can almost never park straight though because of the 4 wheel stearing) fun car to drive. Only problem with her is that she hasn't got much pick up at stop lights everyone blows me away oh well.

My dad is going to be pissed though when he finds out or maybe he will think it was his own fault cause he was messing with it when he noticed there was some fresh oil under the car.

Here's some history about the owner he was crazy about the car he was the 1st owner and now I am the 2nd. Whenever he would park the car in the garage he would put it up on jacks wouldn't drive it on any dusty roads (I don't either) and he wouldn't drive it in any rain or snow (saddly I will have to. The car is way to nice for how old it is!) 100,000miles

Actually, you might just try a new drain plug and see if it will tighten as drain plugs strip out all the time. If the hole is stripped, I'd get a heli-coil (and they sell the kits in most automotive stores) which is a wire coil that screws in the hole and you get a smaller plug (that screws into the coil). I've used Heli-coils from oil pans to intake manifold bolt holes.

I'm assuming that you stripped it tightening the drainplug back in. I would almost put money on the oil pain being stripped, not just the drainplug. If you're looking for a cheap fix, drain the fresh oil, hold onto it though...take off the oil pain (so not to get metal shavings in the engine...) and re-tap the hole with the next size up tap. Get a bolt that size with a 17mm head (guessing...) and have at it. Replace the oil pan gasket too.

If it was just the bolt, which I doubt, just get the right sized tap and run it through the hole a few times.

Regardless though, you're going to have to remove the pan (and replace the gasket if you've got the $$).

off topic...

I remember the last time I had to re-tap a hole on my other Honda. I had been working on the car ALL day replacing the timing belt. I was putting everything back together at about 8 in the evening. I was hungry, tired, and wanted to get it finished up. I cross-threaded the bolt that holds on the A/C compressor due to me being in a hurry. Costed me an extra hours worth of work to re-tap that hole. And then there was that time the caliper bolt snapped when i was changing brakes...we won't tell that story though.

Good luck with your Honda. I have two right now, and they're great, great cars.

Prelude SI? im trying to remember what they had in them in 91.....in anycase, they are quick cars if you put some work into the engine. Put a new intake, and exhaust. They run about 16s stock if i remember correctly, which if farely quick, so give her some quick HP improvements and youll get a little mroe off the start.
