haha seriously they look like that after 20K miles


Someone pls educate me why DI engines do this and foul the engine oil early.


Because the dry soot from the EGR combines with the oily vapour from the PCV to form a thick tar-like paste. The paste bakes itself on with heat.
You would have similar problems if you were to ingest all of your own waste instead of disposing of it hygienicly.
 
If it makes you feel any better, there is a huge problem with oil consumption with the newer Hondas too!

I did not know that. But can they role coal like mine?

It's getting good mileage because it's running on oil instead of gas. Lol

How about pics of the cat?
 
I had a 91 ranger with a 90hp 2.3 blow a plug one time...cost me the engine...had to drive it home 60 miles on 3 cylinders...that truck was a 2 legged dog when running good! On three it was almost tow truck time

Pics of the cat? Or that car typo'd? The cat is original, logic would say it isn't working but it has passed many dyno emissions sniffers in the past.

Nice picture. You must have an impressively small turning circle, better than even a London taxi.

Like the "ghetto" head-flatting method (I might have tried valve-grinding paste direct on the glass) but I'm not clear why you had to do it. Was the head warped (or suspected of being so) or did you just want to raise the compression a bit?

A couple weeks after a thorough state inspection from a dealership my lower ball joint separated after turning from an off ramp.

I'm not familiar with valve grinding paste. I didn't expect the head was warped, I removed it correctly from a wreck with about 120k on it. I intended to clean it up. Right away I could see that it had high spots. 6000 miles so far so I believe I did an ok job.

I keep it mainly to see how long the original engine/trans will go, at this point I'm looking forward to 400,000 miles. When either totally fails the whole car goes to the junk yard.
 
Gasbuggy I'm not familiar with valve grinding paste. [/quote said:
I'd guess it'll still be available, especially in the US. It is/was used to manually lap valve heads to mate with valve seats. Comes/came in a double ended tube with course and fine paste, along with a sucker stick (like a toy arrow) for rotating the valve.

I've used it for that, and for flatting an expensive oilstone on plate glass, a similar but perhaps less demanding application (flatness-wise. An aluminium head will be softer so should be easier to grind).

The advantage would be that you wouldn't have to fix paper to the glass or worry about keeping it flat.

You ground off .030" with nothing more than just elbow grease! That's quite an amazing feat there.
 
If you have a SOHC or DOHC engine and mill the head and/or block beyond specifications, it may interfere with valve timing. Sometimes you can compensate by having a thicker cylinder head gasket.

It was quite a workout. I could be wrong about my guess but on the Honda forums I saw discussions about milling and at what point you need adjustable cam gears. Seemed to not be an issue below .030. When I compared the new and old head I cursed when I saw the difference.

It did interfere with mine, with the cam gears aligned correctly the car was not driveable. I had to set it one tooth advanced on the cam sprocket with the distributor fully advanced to get it running correctly.

But it does run well, here is a video I took after putting it back together.
 
unless you cleaned the egr ports I find it hard to
believe there wasn't any rattle on regular gas. my 95 has over 500k miles on original engine and auto trans without any tear downs ... f22b is one of the best engines ever made

It truely is one of thee best, my A/T is original also. The video gives you somewhat of idea that there is no detonation. I even had it on a dyno at my friends shop, just for fun, and stood right there with the hood up while it did a pull starting from a slow roll in 2nd gear. I've cleaned the EGR ports many times, and also cleaned them while the head was off.
