      Hey folks i just had a terrible oil engine leak
      White Smokin!!
      No im not burning coolant oddly enough
      So the rabbit is down and im planning an engine rebuild
      Total overhaul

      Remove everything from the engine, do transmission clutch plate replacement
      Most likely doing piston ring replacement also

      Burning oil for sure because its blue smoke now that i drained the oil and refilled it to a proper 4 quart approx level

      The rebuild: Remove head, oil pan, pistons, all engine components down to the bare block
      I may remove the camshaft and crankshaft, undetermined yet if needed
      If i do that i will need to replace the bearings and seals
      Well this car has 150,000+ miles on it and i have no previous owner's receipts of work... though It appears to have sat for awhile somewhere and was in a pine dirty enviornment probally dirt road.
      Oil has leaked from the valve cover onto the intake since I bought it

      Any suggestions you guys have for a rebuild?
      I'll take advice you like to give

      Thanks!

      replying to myself to add information...

      Valve stem seals will be replaced also
      Unsure if i need to replace the valves themselves

      I only recently parked it and I will need to move it 4 miles to my garage to dismantle it
      Dismantle should take approximately 3-4 days

      I know a shop near town that does head lathe milling for $75 so thats not a problemo
      always when removing the head do a remill even if it was removed flawlessly without warp

      I have to get my wrecked car out of the garage too... need to salvage it for $200 to somewhere grr... cant anyone use a rare parts car for $200 that starts and drives down the street but has front frame damage!?!
      OK
      So most likely i blew the head gasket, worn valve seals, or piston ring damaged.
      You can guess the general repair work required
      I once did a head gasket replacement on an 88 Oldsmobile in 3 days....
      Problem was i blew up a piston ring instead and that didnt fix the problem

      dismantled engine down to the block and crankshaft
      the transmission work comes after part of the head is installed
      the scoop:
      piston rings flawless
      head gasket flawless----NO LEAK
      piston bore no cracks
      valve damage NULL
      piston impact valve damage -- NULL
      no cracks in head, no damage to head -- FLAWLESS
      oil pan gasket orig
      all gaskets were orig except for water pump housing and waterpump
      ALL GASKETS... some of these bolts were never removed
      so only once was the poor car in need of some "major" service which was the water pump and altenator...
      interesting
      reminder: 150,000 miles
      no sludge in oil pan or engine at all
      just normal typical carbon build and exterior grease from constant oil leaks
      only noticable problem: oil pump filter was clogged with some debris

      i have not removed the valves yet to do the stems, i will get a tool for that tomorrow and begin that laborious task of taking those apart

      white smoke in the cylinder can be oil
      if combusted at 600C it burns white
      just pour some fresh or used oil on your exaust after driving the car a few miles...
      even if it doesnt combust in the cylinder if it gets exausted into the pipe the pipe is extremely hot and will turn it all into white smoke

      since the condition of the pistons and head are in great condition i wont be pulling the crankshaft out to replace those berings
      i have a micrometer or whatever everyone calls it, MIC, ?
      and i have feeler guages and straight edges
      just patience and dedication to the measurement of numbers will lead me to another 150,000 miles

      today i replaced the clutch kit parts and painted the transmission
      transmission parts replaced:
      clutch friction plate, pressure plate, rear main seal & gasket
      throwout bearing, rod shaft seal, output shaft seal

      painted the transmission a dark blue two coats..

      so the piston rings were done and placed back in with no problem
      plenty of spacing left on the rings
      got those spaced staggered when installed

      head went on.... why this head does not have a dowel pin like most head/blocks is beyond me...
      stupid thing wants to go slide off so im standing there with help lifting this thing with the intake and exhaust manifolds bolted on which is probally about 60lbs


      tomarrow more cleaning around the tranny area and some more painting
      then the transmission goes back on and mounts get bolted
      finally...
      then the block can come off its brace and everything else gets slapped on like magic fireworks!!

      like i said, i will get some photos posted here for everyone to enjoy, i know everyone likes to comment on photos

      Interesting paint jobs. Did you actually rebuilt the tranny or just paint it? I didn't see any cylinder honing happening there. Did you just use the drill and sandpaper method and hope that the bore is right or did I miss it somewhere? Did you replace the rings at all? Again, very colourful painting you've got there. Looks neat.

      "no american support here... " WOW! then I'll add this, that looks like crap! what a waste of time! for all that effort you could have at least clean the head so it looked new. looks like you know how to paint. well grab the silver can while your at it. btw I bought my completely rebuilt head from a machine shop for $35. most people throw the 1.7 away. anyways good luck with that ugly non American motor.

      i didn't hear you mention replacing any of the stretch bolts... like the rod bolts, head bolts, PP bolts.. maybe you did.. just thought i would mention that

      Sounds like someone has been looking for an excuse to paint their engine for quite some time. Hope you can get it running again.

      i guess you guys want a list of parts?

      i did not rebuild the transmission because it works perfectly
      why rebuild all the gears in the bell housing?

      yes there are "missing" photos of when i did not have access to a camera
      or maybe the missing photos are because i did not stop to take a picture of before, during, and after and before paint

      but the main project consisted of dismantling the engine down to the crankshaft and replacing all the seals and yes you guessed it, new rings, new seals and everything in between


      why paint an engine? well mainly what is the major concern of oil and dirt being all over everything?
      because its nasty!!


      ok then, ill get you a huge parts list here so you can compare


      oh, yeah.. if you throw away engines like the 1.7 then obviously you have no respect for stock original

      why would you paint your flywheel white? wouldnt it be harder to see the marks with a light now?

      Phew, I would hope you only painted one side! Don't be upset, I think a lot of people who commented on your thread didn't see most of what you did....only the painting. For instance, you didn't mention any of the machine work. i.e. regrinding the crankshaft or even honing the cylinder walls to ensure the new piston rings will seat properly.

      oh

      em

      gee
      A Rabbit is not to be wasted on the tentative or weak. Only the worthy are invited, and then only at your own risk. If you have even a modicum of hesitation, DO NOT buy one of these cars. Instead, leave it for a worthy soul who has already matriculated to the sublime ecstasy of what those in the know refer to as a "MK1"
