my rebuild!
« on: April 08, 2012, 02:09:00 pm »
well i (kinda) rebuilt my first motor yay!
i only did the rings, and the hone, as the bearings looked good, and if this whole thing flies apart in 1226 miles then i'll be out .. less money. another reason i didn't install the turbo as of yet; spend $150 on the fab work to get the turbo installed.. then hone grit wipes out my motor and turbo. so i figured i'd at least wait to install. i got panicky and have it up for sale, but nobody's gonna buy the damn thing anyway, so i'll likely install it after i'm confident my rebuild is good.

does smoke blue now on first start of the day, or after sitting a while. from my experience with fords, this is from excessive RPM and would be the head leaking the oil, but it didn't do this before. although i have run it up to some RPM's since the new rings trying the "get them to seat by runnin the piss out of it" method. any comments there? rings not doing X like they should?

have exhaust leak. that damn toilet bowl situation with the C clips SUCKS. i fought like hell getting that back together, only to hear the sound of a leak.  

oil light wouldn't go out. almost crapped myself.  found head oil sensor wire and temp wire were backwards yay.

also, still running hella motor oil. seems to like it more than ever now.

tl;dr: new rings now smokes blue on start up. why?

Expect smoke for a few hundred miles while the rings seat.
Was the exhaust filled with oilo by  pre- rebuild drama? expect more burnoff.
How far have you driven it?

I snapped a bunch of rings on ether so my drama was oil free. Have driven about 100 miles

I'd still anticipate noticeable oil smoke for awhile, but you could do a comp test to see if one is different than the rest.

I must say this reminds me of the bon ami cleanser being used to seat rings in OLD gassers if they failed to seat

I didnt want to be the one to say "use it"  but thought it could be indirectly brought up for the thought to be tossed around... lol, I really dont know that much about the IDI, some people say that in a carbed engine you are mixing the abrasive cleaner into the air fuel mixture, while in the diesel, your air fuel doesnt pre mix outside the chambers. but yes the fine grit airborne abrasive should have similar results on all engines... as long as the problem is with rings failing to seat. not sticking rings, large ring gaps, broken ring lands, or other such issues

I have heard of that being done on the old two-stroke Detroits....but, that is from the Barney Rebel era.

But, doesn't that grit have the very-real potential to make it into every bearing on the engine? I mean, even using a pop bottle and sand paper is more dignified than THAT! Yikes!

Well, even if it smokes blue on start up, I couldn't be happier.. Fuel mileage is looking good, power is good, idle is so much better now.. Before the idle was a mess, and if it did idle, flip the headlights on and it would kill it!

If it is truly oil-blue at start up, it needs valve stem seals. If you replaced the valve stem seals (does not sound as though you did), you may have damaged one or more with careless installation. If so, it will probably get worse.

100% agree!

i dont think marc's pop bottle was all that bad, myself..

honestly thought it was pretty clever..

the engine was basically JUNK when he started working on it, and he made it better than it was, so it was a SUCCESS if you ask me..
92 Jetta GLI - Black, 1.6D w/ GT2056V turbo..
86 GTI - 4 Door, Med Twilight Gray, Tow Machine..
86 Audi Coupe GT - Tornado Red, All Stock.. WRECKED.
89 Toyota 4Runner - Dark Grey Metallic, LIFTED!

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.

Kinda odd to start immediately after rebuild.. Head untouched.
It's no big deal. Just as long as it's less than a quart per oil change I'm happy

If you seal up all the blowby on bottom, it usually presents itself up top.
