Srsly, though. I've never heard anything positive about running seafoam through our engines... Something about the apex seals....

I would say pull the vac-line on the backside of the UIM, T-off to a line that's about 18" long and drop it's open end into a 50/50 solution of WHITE (clear) rubbing alcohol and salt water.

Start the car and hold the tach at some rev that's higher than Cheech and Chong - like 6k, or something (dammit there's a write up for this).

If you've got enough volume (alot) it'll all eventually get pulled into the combustion chamber.

The reason this works is because it's super-heating the fluid and acting as a steam-cleaner, cooking off the carbon deposits, internally.

You don't want to be behind it while this is going on, either.... You'll not be liking life, if so.

Gigetty.
That's from snake oils and other carb cleaners (which Seafoam is not). Seafoam is seal friendly.

'Tis true! The best way to keep the engine clean is to rev it daily. These engines love that redline. The next step is fresh fluids and filters. Yes, change that fuel filter. The difference is NIGHT AND DAY. Next up, plugs and wires. Finally if you are able to not have the car for a week or two, send the injectors out for service. There is no magic here. the cars are old and have some miles on them, they just need a freshening up.

Seafoam is worthless. It's snake oil. Use carb cleaner.

Is there a final, on this?

I mean one side (supporting the position I've always heard) says to avoid it like that chick in HS with those funky sores around her mouth, and the OTHER side says embrace it like a sorority freshman.

Other than straight distilled water, is there a final on this? Is it dependent upon Apex-seal age, etc?

I live not too far from flushing.

Problem is.... i dont know the compression of my engine and i'm afraid to hit the redline for too long.

Compression is a pretty easy thing to determine. If you haven't ever had the engine open and the seals done, chances are it's reading between 75 and 80 on all faces.

If they HAVE been done than look in the 80 - 95+ range.

Wither way, you're NA, so bipping it off of the limiter isn't going to kill it, as long as you're not WOT, bouncing the tach, for 5 miles....

Maybe.

These engines can sit at redline all day long; they thrive in "race conditions. The only danger in redlining is if the engine was grandma'd it's entire life and NEVER redlined. Maybe then something bad would happen. Maybe.

+1. For sure, man. If the top of the tach is foreign territory, to your engine, it could cause problems, but if the seals have been re-done, then there shouldn't be any issues.

I know my old GXL and GTU seemed to perform REALLY well after running it in the nose-bleeds of the tach, for a bit.

I put a dab behind each ear in the morning. Drives my wife wild, coincidentally my hearing has improved 99%! Its like magic!

But on a serious note, it really is fantastic stuff, I would recommend using it.

That's because high revs in a rotary also help clean carbon (from what I understand).

I bought this car a year ago. I have no knowledge of the engines condition, nor do i know if its been rebuilt. I'm going to assume that it wasn't babied though, just from the sound of my tranny.

I have no cold/hot starting problems and it never floods. Like i mean NEVER. I could go in the coldest morning and start it up for 2 seconds and turn it off and it'll still turn on again fine.

I'm just too cheap to buy a compression tester i was hoping someone nice from the rotary community could help a brother out

An easy way to tell if it's ever been into is pretty simple:

LOOK.


Check along the standard seals, oil pan, waterpump housing, etc. if you see RTV, then dollars to doughnuts, it's been in.
