Have all the parts in except rings. Speedbuggy is in the garage and will not come out for a few days to a week. This has been a long time coming. New valves, valve seals, head bolts, fuel injector, cam seal, rings...
Fire away metroheads with comments and suggestions, this is goona be fun.

buy another cam seal and replace your crankshaft seal with it. return your headbolts and buy geo glenn's reusable headbolts. make sure to install the rings correctly. make sure to install the rings correctly. make sure to install the rings correctly. chop the timing cover up to where it only has the timing marks the nut hole and one bolt hole. paint the timing marks on the sprockets with white out. be careful when reinstalling the pistons to not mar up the crankshaft bearing surfaces. make sure to install the rings correctly.

How do I install the rings? hahaha Good point(s). I already have headbolts and valve seals from Glen. Replaced crank seal about 4500 miles ago.
So far...
Removed distributor
drained coolant and oil
throttle cable
Exhaust manifold-------saoked nuts and bolts with kroil. Let them sit and they came off without a hitch. Love that stuff.
Where do I disconnect the O2 sensor from the harness?

Next will be belts, oil pan, vacuum lines then the head hopefully all that by tomorrow. Keep the pointers coming, it only builds my confidence. Thanks

Leave the 02 sensor alone. Keep it inside of the exhaust mani unless you are going to replaceSanit.

Are you taking the engine out of the vehicle?

Will you hone the cylinders?

While in there replace the rear main crank seal and hit the clutch plate/flex plate with some sand paper(if a 5spd)

Got it about the O2 sensor, Just did'nt find where the O2 sensor unplugs. Leaving the engine in the car. Going to hit the cylinders with a dingle-berry honer to deglaze and add crosshatch. Whats the best honing fluid to use? WD-40? Motor oil? Dont have a clue.
Next project(s) new exhaust then suspension. Dont have enough foldin money for the entire thing.

Another thing I noticed today, should I take the thermo housing off of head while cleaning and replacing valve and components? There are no water leaks there and the car runs at normal temps.
Still cant believe the exhaust mani came off that easy.

DO NOT HONE THE CYLINDERS WITH THE ENGINE IN THE CAR. DO NOT DO IT!!!!!!

Why, you might ask? Because the honing will create dust which you will never get out of the nooks and crannies while the engine is still in the car. You can get the dust out of the engine properly if the engine is on a shop bench.

Once dust gets between the crank shaft and bearing surfaces, then your hard work to rehab your engine will be thrown out the window because after a few thousand miles the bearings will become galled and pitted.

Please continue to ask questions. We are here to help.

Yes, take the thermo housing off the head. Get a new gasket for it.

A spring compressor will come in handy when extracting the valves.

How many more miles can I expect to get on my three cars I honed the cylinders in the cars than I have already got? Been atleast a year on all of them.

All I'm saying is , better to be safe than sorry.

Yes I am the king of frugal metro engine rebuilds, but I have never honed an engine while it was in the car. I'm too afraid I would never ger the grit completly out. One the other hand i will reuse valves, head gaskets, crank bearings and maybe even a head bolt or two. But I will not hone the engine while it is still in the car.

:gp

I have gotten over 60k out of engine that had the "Hone of Death". I just stuffed rags down in the cylinders to protect the crank from dust and honing residue. Hit the cylinders with some WD-40, and just honed them enough to scuff them up and put in a nice hatch pattern. When I was done I hosed everything down with a couple cans of brake parts cleaner. Then a bit more WD just to make everything slippery again. The bottom ends of these motors are pretty tough, it's the heads that are weak. My engine was not particularly well taken care of, and there wasn't the slightest ridge on the tops of the cylinders. I don't really even think I needed to re-ring it. All the rings were free in their grooves, and there wasn't even much gunk in them.

I am not frugal, but lazy when it comes to rebuilds. I don't want to be tracking down special tools, running back and forth to the parts store or machine shop, screwing around with Plastigage, etc. I bought a newly rebuilt cylinder head off of Ebay. It was $199...shipped. Drop your old head in the box, slap on the prepaid return label, and send the core back. Swap on all your stuff onto the head, hone the cylinders, put in new rings and bearings (with assembly lube), and slap it all back together.

You are done.

I am the one on the left.

measure and check, check and measure
good luck with your rebuild
never fails- you cut TWICE and it will still be too short.
man - take out the block and save your back- bending over the firewall to hone it, and making sure your passages are clean- what a PITA.
If you don't have an engine stand- a few fine folks on here built a wood cradle to hold it- c'mon- the motor is tiny- you can do it.
