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

correct me if im wrong but are early 18rg heads(210,230) supposed to be single valve spring?

**o_man_ra23** · 23-02-2008, 06:41 PM

I think they may be Hosking... I believe they were single. Precision springs do double valve spring kits for early RGs... not sure the specs, didnt think to get them when I had the springs ordered.

well this is what i got when i pulled the no 4 inlet valve out

and the ports on this head are alot bigger than the ones on my 253 head so i suspect some head work has been done in the past

Quite possible... I have a feeling you got lucky on that one mate. Nice.

Nah, all base settings and timing is fine.. Tuned up on dyno by an old school mechanic.

i suppose that makes up for the gay (8.3cr) pistons

**o_man_ra23** · 23-02-2008, 11:40 PM

My CT26 makes up for my Ghey 8.3 pistons

(and the fact that they are .5mm o/s genuine Toyota items)

my 18RG RA28... dissappointing reality check tonight, just got back from willowbank, after clocking a very sedate [email protected] and i had to limp home with a busted pinion bearing... first run was a [email protected]... just to rub salt into the wound, Dana (Sillycar chick) managed a best of [email protected] in her hybrid 2/3T TA22

**o_man_ra23** · 23-02-2008, 11:53 PM

Ambient temp of LH engine bay is about 80 degrees at idle..
and yes, before i get any comments, the car needs a good clean

**hosking1991** · 29-02-2008, 10:23 PM

well i bathed my rods in the hot acid tank at work for a week and also cleaned up my other pistons (the less ghey 8.7:1cr

) i sand blasted the valves a faced them too

also my 18rg spare parts keep buildinng up

(toymods youngest 18rg parts horder

)
oh and i didnt drink all that vb

and before i go a close up pic of a 230 and 253 inlet cams (230 left)

**RAd28** · 29-02-2008, 11:53 PM

the acid tank you have at work, what kinda acid is it using? is it something like sulphuric acid (diluted) or is it something much more gentle like coke or even molassas?

**hosking1991** · 01-03-2008, 12:03 AM

not too sure rad never thought of that but will ask. at work we class that tank as cast iron so all our rods and cast iron heads go in there it brings the heads up nice if you leave it over night and for the pistons i put them in the alloy bath for 5 mins and scrubbed them them and soaked them in the kero for a couple of hours

**hosking1991** · 01-03-2008, 05:36 PM

cheers

**RAd28** · 01-03-2008, 06:05 PM

cheers, would like to know what they use to clean parts up at those places,

as for the workshop manual, i have one of the green books which is immensly helpful, pretty sure you can get them off ebay for $30ish

EDIT: Woot... i got something right

(Ebay link) This is the "RARE" type... don't believe me? well it's the only one on ebay at the moment... can't get rarer then that!
