I have a 98 Eclipse GS-T Spyder with a built 6-bolt 2.3L stroker motor and a 75trim turbo setup with wastegate, bov, big front mount intercooler and the usual stuff. My friend just seafoamed his car and it seems to run a lot better now, I was just wondering if it was ok to seafoam my car as well and if so, where is the best place to put it? My friend sucked it in through his brake vacuum line.
Yeah. Search it. It's a great way to clean out all the crud in your engine. I know you can suck it in through a vaccuum line, but I'm not sure which one. Be prepared for a crazy smoke screen, though.

Alot of my subaru friends swear by this stuff. Honestly though, I'm too scared of having that stuff pulled into the motor.
If you search on honda-tech, you should be able to find alot on it. Generally, most honda people suck it through the large vac. line that runs to the break booster. Since we don't have that, I would say use the largest vac. line you can find on the manifold. Take your time and do it slowly though. Remember that seafoam is a liquid and liquids don't like to compress, no matter how much your pistons want to. If you get too much in, there is the remote chance of hydrolocking your motor.
Ok, thanks for the info, I've seafoamed my 3000GT SL plenty of times before, I just wanted to mainly make sure it was safe to seafoam my car with a turbo setup.
That shit scares me, so I've never used it. But it sounds like plenty of people have, so I may try it. OP, if you do try it, make sure to post your results!!!
If you used a small vacuum line to suck in the liquid, you should have no problems with hydrolocking the motor. Have someone rev the motor to about 2000 rpms and then put the vacuum line near the surface of the seafoam liquid. Don't submerge it as it will make the car want to stall out. Takes about 15-20 seconds this way to suck in all the liquid and as soon as that happens, shut the car off and let it sit. Follow the rest of the directions on the bottle and you will be fine. I've done 2 cars now with this stuff and it was easy as pie.
As far as my understanding goes, seafoam is for cleaning our carbon deposits in the motor so i'm not too sure if it would cause a bunch of leaks. Then again though, I thought the same thing about switching to synthetic and ended up spending the next 2 weeks replacing every gasket trying to get all the leaks to stop.
I switched to synthetic immediately after buying my car, changed the oil like 3 times in the first month, just to try and flush the engine, since it sat for a year or so. I was so worried about leaks, but guess I got lucky. I would like to try seafoam, but I'm still worried about leaks.
I have used Seafoam in my Spyder twice with 127000 miles on it now. I use the pcv valve and control the flow going in and then pull out the plugs and put some in each cylinder and replace the plugs and that is it. I have done the same on a toyota corolla and nissan sentra as well. No worries, It is a lot of fun!
