Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive So I haven't posted for a while, mostly because I have started to use a camera and have since lost all of the photos.

So the long and the short of it is, that I got the head back on, the engine running and everything good; even booked in for rego. Then the welch plug in the back of the head that I hadn't seen while it was off began to leak. Badly. Eventually I managed to not get it out with everything in place so I ended up taking everything off again including the head. With the head off it took all of around 10 minutes to remove and then install a new welch plug. With everything back on I got it started, no leaks. Phew.

From there I got it registered, drove it for a few weeks, took it to Sydney. Took the old oil that I'd put into it out and replaced it with fresh stuff. and gave it a good clean inside, still needs one outside though.

After Driving it for a while I noticed a strange noise from the front end while in 4wd mode. Solution 1, change the oil in the front diff and check what it loos like inside. No dice. Next, start researching online. One option seemed to be that it was "Angry Sparrows" or a squeak from something potentially worn in the front drive shaft. So off with that. It turned out to be a piece of cake, just 8 bolts to remove. Upon inspection I discovered the the apparent reason for the noise was a lack of grease in the ball in the middle of the double carden (CV) joint near the transfer case.

After pulling the double carden apart and damaging(?) one of the universal joints grease was worked into the ball because a replacement kit was around $100 which is somewhat more than I was willing to spend. Everything got re-assembled and then a short drive was taken. Silence, no more angry birds for me.

With that fixed I started to think about the trip I am leaving on tonight and the fact I will be towing a trailer ~1000km each way in an automatic of less than ideal status. I looked into a transmission oil cooler and discovered that there was already one installed. I also wanted to be able to measure the oil temperature so I installed a SAAS oil temp. gauge as a transmission temperature gauge. The install was very straight forward and didn't take too long except for the cutting of the hard line. That had to be done by hand with a hacksaw blade as we had nothing else that would fit in the small space.

So from here I have a 3 new projects all of which are exciting and I am looking forward to all of them. One involves a road trip this weekend, one involves rainwater and the last involves my wreck, EFI, turbos and someone else's car. All will be exciting and lots of learning will be done in all 3 new projects.

Until next time, Cheers.

Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive Last night I got the head removed from the XJ Jeep Cherokee I've been working on. This is what it looked like before I started:

I decided to leave both manifolds on and just deal with the extra weight. It was heavy but it was still easier to do that than remove the bolts that are hidden under the intake manifold.

It's not very obvious but on this bolt there is a very thick black gummy something all over the threads. Not sure what it is but hopefully I'll be able to clean it off before I put this all back together.


Here's a shot showing my highly sophisticated lifting mechanism with it halfway out:
One of the bolts on the top for the manifolds is pretty well in the middle weight wise front to back so with the chain over that. With the chain secured I put a foot above the firewall and another one above the radiator; and lifted. Thank goodness for joining a gym is all I can say. I was able to lift it and with my able helper guiding the head I could move it between 1' and 6" at a time. Everntually I got it off the car and a bit lower, this is what it looked like then:

From there it was fairly easy to get my hands under it and carry it over to the bench; where it got turned over for removal of the gasket and preliminary inspection:

The gasket is still on here, as you can see near cylinder 1 it seems to have blown out completely and around cylinder 6 it's deformed and blown into the cooling jacket. Not good, you'll see the results of that a little further on.

It looks like when I had gotten it running cylinders 1 & 6 weren't working at all and as such don't have any sooty buildup in them. The other 4 cylinders do which makes me think that it possibly wasn't running properly, but that may have just been because it was cold and only had 4 cylinders going.

One more interesting point here is the exhaust manifold. From the build quality I hope nobody was paid to do it. The welds are not very fine and there were long bits of welding wire were sticking out in a few spots.

This is what the block looked like once I got back to it:


Not a very pretty sight. Just to see what would happen I tried turning it over with a socket. This went well and pretty easily. This allowed me to get that water out of number 6 and get a good spray of WD-40 over everything to help reduce any corrosion that may yet happen.This is what it looked like then:

Most of the water in Number 6 ran out over the back of the block. So it will only need a little bit of mopping to get the rest out.

That's pretty much all there is, from not it will just be cleaning up parts, checking tolerances and buying replacements for a little while. So if I don't post for a little while don't worry, just getting everything prepared for the next stage. Write comment (0 Comments)
Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive Not much to report tonight, pretty much got everything sorted for removing the head tomorrow. Got the exhaust disconnected from the extractors from under here:

And above here:
That was probably the nicest pair of nuts to undo today, even though there was only enough space for the ratchet to move 2 or 3 clicks at a time.

Got the bolts holding down the head off like this:

I only got to this state after removing a 11/16" nut holding down an earth strap. Unfortunately I didn't realize there even was a 11/16" spanner in the house, let alone that was the size for a good 20 minutes.

Also the manual says that the bolts holding the head on are 1/2" or 13mm. I tried them with a 13mm spanner and started to strip the 12 point head so I decided to buy a slightly smaller 1/2" deep socket. The fun thing about the 1/2" deep sockets sold at Bunnings is the hole in the middle is tapered, with the smaller end towards the bolt. This meant that the brand new tool I'd just driven across town and bought was actually not going to work. So after messing with sandpaper and getting nowhere a round file was found that was used to enlarge the narrow end of the taper just enough to be able to be pushed over the studs. However that is still not the end of the story. Because after loosening some of the bolts the socket would get stuck on the stud. The solution involved a hammer, a 1/4" drive socket extension and a sharp corner in the engine bay. By putting the extension down the middle of the socket so it was resting on the end of the stud, putting a sharp corner in between the socket and the stud I was able to tap them out. Thankfully.

By this time tomorrow I should have the engine in halves and some very interesting photos to show just how bad this engine has become. Write comment (0 Comments)
Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive So I didn't end up getting much (Anything) done on the Jeep last week and the weekend was busy with sailing on the James Craig and then doing maintenance at the Zig Zag Railway. However yesterday I feel I made some good progress and got the rockers and pushrods out. I also got the bucket with the old sump oil out from under the car. This is what it looked like after I pulled it out:

You can see some little bits of green from the coolant that has been getting into the oil.
This is what it looked like aft I stirred it up a little. The same as when it came out originally.


I also got the rocker cover and rockers/pushrods out.

It was pretty awkward to get to so this was how I was getting to pretty much everything:
There was also a bolt hidden right at the back that I had no hope of getting a socket onto it so back to doing it the old way with a 5/32" ring spanner. Once I managed to find the damn thing and get it undone this was the sight I was met with:


Yes that is more nasty oil on the rockers and even little drops of water on the bridges between the intake and exhaust. That's how much water was in the oil, not good. We'll have to see what else is going to be going on and broken in the next few days getting further down into the engine. So this is what all that looked like after being removed from the engine:


There's a lot of that nasty oil that will need to be cleaned up and hopefully there won't be any surprises while cleaning it all up that can't be at lease ignored until we squeeze the last few thousand km's out of this engine before it is going to need more work than just a gasket.

Today hopefully I'll get the exhaust undone from the headers which should be the last thing left to do before finally removing the head completely. Write comment (0 Comments)
