For the love of a tractor engine: The life and times of the 18R-G

If its running a Bosch dizzy then it would be the same as the 18RC.

Crowncustom, all 18Rs run NipponDenso electrics. Bosch make aftermarket replacement parts for them cheaply. Yes the points from an 18RC will fit, but there were a few different 18RC dizzys, so its best to take your original points in to match them up. Same goes for rotor button, dizzy cap and condensor. I have been caught out a few times with this (forget sometimes)

Any suggests RE carby problems?

Not all 18RC powered Toyotas ran Nippondenso electrics.Most of the Australian assembled Toyotas from roughly 78 on had Bosch dizzys,starters and alternators.

okay guys, was speaking to Leso yesterday, checking a few things between engines and we noticed that my block is different to either of the 2 18RG blocks he had, OR the 18RC block he had there... my dizzy mounts differently (though in the same spot), i have a stud in the block on the lower rear side of the dizzy, where as the others had a tapped hole on the top forward side of the dizzy, also the crank case breather on mine has a large weird thing on the extractor side next to a small blanked off hole (has bolt in most cases) but in my case, the mount for this weird thing is cast into the block, whereas the other block we had were void of any such mount. they did their breathing through a plate just under number 1-2 runners on the manifold which i'm sure your all familiar with.

what is my block from? can i ditch this weird breather thing? can anyone suggest why i'm flat spotting above idle? how do flys land up side down on the roof?

Yep I'm using a 2JZ filter on my 18R-G. With EFI the stock 18R-G filter won't fit at all, it fouls the plenum.

Here's a photo with the part number clearly visible (it's the one on the right). This same filter is used on lots of Toyotas so your local dealer is guaranteed to have one in stock.

Can someone confirm something for me? I cant remember who gave me the part number, but I have a part number for 18RG oil filter is 15601-33021. When I first did the oil change on RAd28's 18RG, toyota wasnt open on the weekend and needed an oil filter, Aussie Auto matched up the equivalent Ryco oil filter based on the toyota filter. It looked about the same height as the one on the left of the photo. If thats the 18RG filter, is that what River, Witzl etc all use on their cars and swear by? The filter on the right is also a 2TG filter. We all know both of these engines 2TG and 18RG have oil pressure problems on start up if the wrong oil filter is used, and you get bad chain rattles etc. Why then are they both different in size? I take it then based on Norbie's post that you can use the filter on the right on an 18RG?

[Norbie]

Yes the filter on the right is the one I use on my 18R-G and have done since I did the EFI conversion many years ago.

Rattling on startup is usually a result of using an oil filter with no anti drainback valve, ie the oil pump has to fill the oil filter before the engine sees any pressure. With an anti drainback valve the oil filter stays full so you get oil pressure sooner on startup.

RAd28... got a photo mate??

Cheers, Owen

[Sagluren]

so the smaller filter should get rid of the bad oil pressure at idel as well, i have this on my 18rc and cant get rid of it.

[o_man_ra23]

Should help with startup as there is less volume of filter to fill on the pump side of the anti drain back valve.

Cheers, Owen

[Sagluren]

cheers man, wasnt sure if it was a rg specific fix.

sam.

[o_man_ra23]

you need to pull the shaft out of the middle of the 18RC filter holder (or cut it to size) to fit in the shorter filter.

Cheers, Owen

[Sagluren]

can i just use a pipe cutter, does it have to be a certain length, anything else i sould look out for.

sam.

[o_man_ra23]

short enuf that it doesnt get hit when you screw the new filter on. Pipe cutter will be perfect.

Cheers, Owen

cheers man.
