I've posted this on another forum, but for those of you who reside here, I'm posting it here as well.

I couldn't decide whether to title this "Change your oil" or "Cleaning internals on a budget"....

it's actually a bit of both.

Firstly, CHANGE YOUR OIL! :)

A few years ago SKY031 came to be in my possession as a stolen recovered vehicle.

In the first few months of owning it, the rocker cover was removed so that it could be painted/polished.

When we removed the rocker cover, it became quite apparent that it's previous (south australian :) ) owner hadn't been terribly fond of changing the oil, and it was full of crusties.

We picked out the worst of the crusties, and then did the usual, changed the oil, did an oil flush, changed the oil again, and hoped for the best.

It was only a matter of time until something broke, but in the meantime it was still working, so in the spirit of "if it ain't broke don't fix it" life went on.

Well........ it finally broke. :)

Unfortunately I didn't get a pic of inside the rocker cover once it was removed, but to try and give you some idea of how vile the engine was inside, here's a shot of the rockers.

Needless to say, these needed to be cleaned before they were put back in.

Tried detergents.

Tried solvents.

Didn't work.

Turps won't budge 20 year old crusties, even with a toothbrush and lots of elbow grease.

Just as it was starting to look as if the internals were going to need to be cleaned by a pro, I had an idea.....

Which every day household product could accomplish such a mammoth task?

OVEN CLEANER!!!!

So out came the oven cleaner, and wouldn't you know it, the can was 99% empty. :)

Off to the supermarket I go.

Home brand oven cleaner $2.55

Home brand gloves .54c

Home brand toothbrush .55c

The satisfaction of being able to do it in my own backyard, priceless! :lol:

Here is a pic of what they looked like afterwards.

-take into account that the first image was taken in full sun.

the "after" shot was taken in shade, and dulls the shine a little, but you can still get an idea of how well it worked.

So to stop this from happening to you, give your car an oil change for christmas. ;)

Wow.

When I first looked at pic 1 it looked as though they were chipped and pitted etc.

After a while I realised that this was just the "crusty stuff" that you mentioned.

I change my oil and filter every 5,000 and find it hard to believe that anyone can run their car up to the point that you showed.

Shame.

ps. change your oil !

You do realise the active ingridient in most oven cleaners is sodium hydroxide... aka caustic.

Which is fine for steel, cast iron etc but not for alluminium, lead and other soft metals.... ie. it will eat it.

It is the same chemical used in the "hot tank" at engine shops.

I should have also gone on to say that all components that came in contact with the oven cleaner were washed extremely well with detergent and 2 different spirit baths so that no contamination was carried into the head... we also toyed with the idea of sticking them in (someone elses) dishwasher.

If any "melting" occured it would be a shame...

I'd be terribly sad if the tired old RB30 had to be replaced with an RB26. :lol:

    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
