Previous Owner horror story and some more questions!!

Ok wow, well it looks like the previous owner didn't really keep up on anything. I'll let some pictures do the talking.

The Egr

The Egr passage on the intake

Inside of the valve cover

What the block looks like (No I haven't scraped the gasket off yet, yes I am going to clean the check valve)
Posted Image

Cylinder 1 (I rotated them all so you could see what the inside looks like :scared )
Posted Image

Cylinder 2
Posted Image

Cylinder 3
Posted Image

The Head with valves ooh toasty
Posted Image

The head without the valves (notice the hammer and socket lol)
Posted Image

Ok now for the Q&A

*The egr I'm just gonna blast the piss out of it with carb cleaner, then hit it with some heavy duty pipe cleaners. usually does the trick

1. How does the valve cover look? Should I just spray that with some carb cleaner and scotch pad it?

2. Obviously those pistons are a mess but more importantly is the rust on the cylinder wall. Should I just push the pistons out, clean those buy a hone for my drill and hone the block? If so what grit hone? (17v DeWalt & 18v B&D )

3. Whats the easiest/best way to clean those pistons, valves and head? (I have new SS 3 tech exhaust valves) I have no chemical tub or anything like that. Should I just buy a wire wheel attachment for my drill? <And on that note what kind of wheel? I've heard I should buy only brass because it's less aggressive

1,000 Thanks for any help guys, and I've looked up several things with google I was just curious what people had to say about my specific shitty situation.

*Also I bought a strap wrench and it didn't help me get the cam sprocket off... I'll probably just take it to the auto shop at my college and see if they'll just impact it off.

Oh yeah almost forgot

Here's what my cam looked like on
Posted Image

My crank timing sprocket? (not sure if that's what it's called) I'm assuming those little chunks missing is bad...also the key in-between those two bolt holes on the right that looks bent
Posted Image

Should you be able to see the flywheel like this? just wondering. Also check out my sweet ultra poormans ghetto fix on the exhaust that's falling apart. But it's ok because I get my taxes in a few days so I'm probably just going to get nice exhaust

Check those passages well where the egr bolts up too. Make sure you can blow thru both holes freely or better yet clean them out well with a wire brush. I have had good luck cleaning parts like this,

Having a machine shop vat it for you is the best way.

I went to autozone to buy a hone and it turns out they have one they loan out so that was cool. I also went to Farm and Home and bought a few wire brushes and sanding tools. (they were all like 2-3 bucks each so i figured no big loss if they didn't work out)

I did a test run on an exhaust valve because I won't be using them again anyways. I was just wondering what you guys thought of the results? Obviously the valve is shit, pitting and whatnot I was just curious if this amount of carbon removed would be acceptable for the intake valves?

Posted Image

here's what the one I did ended up looking like, I didn't pre soak it or anything and I wasn't sure how much to remove. The brass wire wheel/brush didn't damage the valve which was sweet

The EGR doesn't look too bad, mine was completely clogged. Valve cover looks fine. I don't know what exactly happened to your pistons but they look like mine did when I had a blown HG. You shouldn't be able to see your flywheel like there, there is a cover that's missing. The rust in your cylinder walls looks like surface rust, hone it and see what you get.

Let's continue where you left off..............

Drop the oil pan.
Remove the connecting rod caps.
Push pistons out with a wood dowel.
Save bearings and caps keep pistons and all in order.
Inspect all bearings, only replace if shot.
Remove piston rings by rolling them off.
Soak pistons overnight with purple power.
Clean piston tops and top sides (not skirts) with wire wheel.
Clean piston grooves with pick or old ring. (time consuming)
Liberally spray oil in cylinders.
Hone each cylinder 10-15 seconds each (pull out with drill running when done)
Clean the fuck out of the cylinder walls.
Check ring gaps in all cylinders.
Lube the fuck out of cylinder walls with motor oil.
Carefully re-ring pistons and install with ring compressor.
Careful to put crank with rod connection down before installing piston and don't nick crank.
Remove fucked up crank gear and replace crank seal. (see how to)
Find new key and crank gear and check slop in crank with new key.
Of no slop, install crank gear and bolt and torque.
If sloppy, pack with JB Weld, estimate "center" and install gear and bolt and torque.

Use head repair guide to do head. To clean carbon from intake valves, use a small hammer to break it up and chisel off carbon with a good, sharp, small chisel (do not use a vise or vise grips to hold valve, use hands) and the seat area will clean up when lapped in.

Good luck!

Use new head bolts.
Already covered, grabbed a set of 3 tech re-useable head bolts :rocker . Preparing for the future!

Not great but not so bad.

Get yourslf a factory service manual - you will pay yourself back many times over with the frustration it will save you (ebay is your friend here).

Check the head for flatness. Either have a machine shop do it (best) or you can get a rough estimate with a framing square and feeler gauges. If not flat or the sealing surface is pitted, get the head surfaced. There is LOTS of material on the head that could be removed if required (I've read as much as 100 thousandth...)

Buy a decent head gasket, I've had good luck with Felpro - avoid Apex and Evergreen (unless you really want to do the job twice).

lubricate bearing surfaces as you re-assemble them. You can use motor oil - I like Lubriplate assembly lube.

Get a new O2 sensor, after the abuse the old one has suffered to get to this point it's not likely it will perform properly. Get one with the proper connector already on it, avoid the generic version that would require you to splice on the connector.

Get a new 195 degree thermostat, buy the better version here. Best kind has the little jiggle valve.

Clean all the grounds in the engine compartment.

Good Luck! Keep us posted.

Some Updates!

So today I dropped the pan, got the pistons out. They're soaking top down in milk jugs now. I also honed the cylinders. The end result of the hone is great. No more rust or blemishes, it was easier than I thought. I used new oil for lubricant.

I also cleaned all of my lifters carefully. I did not fill them up but there's probably a few drops of oil in there from making sure everything was lubed well. Before they wouldn't move by hand at all. Now they all work perfectly so springy and clean.

I cleaned one intake valve with the wire wheel. How clean should they be when I'm done? (I'll add pics tomorrow after school_

When you first fire up the engine the lifters will clatter for several minutes until they pump back up. Good for you for resisting the urge to fill up the lifters with oil, a few drops is exactly what you want but not more or you run the risk of the lifters being too full and holding the valves open.

I've cleaned intake valves down to the level of getting rid of the carbon deposits (had to scratch the carbon off with an pick), a rinse with some carb cleaner, a light coating of oil on the stem and reinstall.

You're progress sounds good.

Ok so my pistons sat top down in a carb cleaner milk carton. They cleaned up really nice. I'm going to use these super cheap toothbrushes I got at walmart to do the fine detail cleaning to get the little bit of gunk left.

Piston 1

Here's the bearing on piston 1 they all look like this. So are they fairly even?

Piston 2

Piston 2 under the bearing. How do I clean this? carb cleaner and a scotch pad?

Piston 3
