Per my vin and code on the fan housing I’ve assumed I had a 2.0 engine. Now that I’ve started to break everything down I found an engine code under a few years of dirt and grease that tells me I may have 1.8. Next step is to remove cylinder heads to measure bore and stroke to confirm. I’m not planning on splitting the case. Yet. My question is how do I remove all the built up dirt grease and grime to remove the cylinder heads and cylinders? I don’t want to get into a situation where I contaminate the case with a bunch of shit falling in.

Hello,
Purple power and steam cleaner/pressure washer. Seal off all openings with rubber stoppers. Put the valve cover back on and wrap the dist. up with a couple plastic bags...and spray away.

You can also check the clutch & flywheel you removed. The 2.0L is 228mm size. The part # on the flywheel will tell you if it is meant for a 2.0L as well.

What is your goal here?

It’s an engine m not a neuron. It’s full of carbon, tar, and bit of metal from whirring things banging into each other. The bit more dirt that falls in from the outside will come out with your cleaning of the case, anyhoo.

I agree with Mike on that. Unless you plan to spend the money and tear it apart if it is not a 2.0, what purpose does it serve to take things apart just to know what it is? You may find that you create problems that you do not need.

To identify that engine, just remove the valve covers and note the spare number casted in heads.
The 1.8 l buses have shorter gear ratio, final drive, than 2,0 l, which started 8´75, model 76
But 1,8 l heads would fit also on 2,0 l engines and can have sodium filled and larger exhaust valves. These heads have more solid "meat" around the sparkplugs, than the 2,0 l heads.

My original goal was to take it apart to inspect cylinder heads, cylinders and pistons. I have a good leak between the case and cylinder and cylinder and head on number one and maybe number 2. I’m not pulling apart just to identify things. I don’t really care just want make sure I’m going about it the right way.

you can measure every thing when it is apart. If you have the head off you can even measure the distance the piston goes up and down in the cylinder to get the stroke.

unfortunately just measuring the bore will tell you nothing. Both the 1.8 and 2.0 have a 94mm bore. It's the stroke that makes the difference.

I thought the 1.8 had 93mm.

93mm is a 1.7

I've used a bit of carb spray. The pressure combined with chemical cleaning helps. Leave the pushrods in the case when you pull the head. It helps keep the case cleaner. Time spent here is very well worth it.

How was this engine running beforehand? If it made good oil pressure, i wouldn't split the case as long as you've kept it free of grit. You can pull the lifters with a magnet and learn a lot visually. Post pictures of the cam through the cylinder bores when you get them off.

Every twenty minutes of disassembly is approximately an hour of measuring and four hours of cleaning. Be mindful of the end goal as you go forward, making sure what you're doing doesn't make it worse.

It figures that my pistons/rings have gone up more than seventeen gazillion times on their own, and the worse damage they ever experienced was when my hands pushed them down one time.

Im being pretty deliberate and taking my time. I’ll post some pics when when I make a little more progress.

I believe 1.7L pistons are 90mm and am sure 93mm pistons are 1.8L
