Series 2A with an OLD 202!

So im planning to recondition the cylinder head and replace valves of the 202 for starters to reduce the blow by. Evident through the chuffing of the engine. (block and rings will be later as its not blowing any smoke at the moment)

Im wondering is sitting on 3000 rpm at 80k's per hour gonna really stress the engine, ive been told that they dont enjoy higher revs for long periods unlike 186 engines...



P.s. How normal is it for high range to pop out during long decents?

And on the very rare occasion 4th will pop out....

Is this just selector forks wearing out?

with future plans of rebuilding the gear box what should my level of concern be? 1-10?

Shhhpanks

Looks like yours has all the same issues my brothers old 202 powered IIa had. Can't help with the gearbox issues - we just used to live with it. As far as the engine goes, many moons ago I used to work on these on an almost daily basis. 3000rom for long periods will not hurt the engine if it is reasonable nick, just start sucking the juice. Check to make sure the valve train is in good nick, and adjusted correctly. Carby wise I would look at replacing it if it is only the standard single barrel strommy. There are heaps of different ways to go carby wise, from the 2 barrel holley as mentioned, to SU's, or a 2 barrel weber which I have done a few times on road cars with good results, but not sure of these on hills... If you search around, there are a ton of different manifolds available for 202's. If you upgrade the carby, do yourself a favour and do the ignition at the same time. Source an electronic dissy from the 202 blue motor (VC-VH commodore) Also, if you have it apart, and it has a fibre cam gear on it - replace it, as this is one of the most common failures you see on these as the K's get higher. The aftermarket alloy gear is the go, but you may have to drill out the oil supply pin hole a bit, as they have a tendency of being noisey - if you can hear it over the rest of the noise the IIa makes...:D

AHH ha...

Excellent, engine is untouched as far as i know. Dad never looked after it properly, so i would say valves operating since roughly 1971-2 (hq) would be the first thing to change out.

Recently replaced all the gaskets on the carbie and checked for wear, of which there was not very much.

I figured gears popping out was just one of those things...

ok so the revs are not gonna worry a healthy engine tooo much...If it drinks fuel then so be it, ill live.

G'day COFFEY76 :)

If that red motor has blowby, then it needs rings,it probably has broken ones in it, that is why it is Chuffing through the breather and oil filler, it was a common problem with Red motors,for what it will cost to reco the red motor I would suggest you get a Landrover 2.25 motor and replace it, it will be much kinder on the gearbox, as Holdens will break them, your torque range (pulling power) will be correct for the gears and diffs, and you should be able to comfortably sit on 85-90 klms. and the fuel usage will be about the same 15/16 mpg, if you are going to use a Holden carby on the 2.25 Landrover motor fit either a 49 or 51 main jet as the Holden main jet is to big for the 2.25, and it just pours petrol down it:( the smaller mains were what went into the Grey motors (138 ci) and the 2.25 is 139ci ;)



cheers

Hmm yet to price repairs that were planned for the 202. So once they are known i will be able to plan any further steps.

It was originally a Rover 6 (altered firewall) so if i were to change the engine i would lean more to replacing with the 2.6 over the 2.25.

What are the odds of finding a 6 cylinder compared with a 4cylinder engine???

and price difference?

Im not against swapping the engines over, im more concerned with avaliability of parts and more local knowledge about a holden motor over a rover motor.

The incorrect gearing for the 202 is already quite annoying.

Beter to get an adjustable main jet and get the mixture dead right.

If you want a six i would go with the holden as the it is a more reliable engine in some ways.
The landrover six drank fuel like it was going out of fashion. It was nice to drive and low down torque. If worked hard it can burn exhaust valves.
The 2.25 was a far better motor, IMO, as it was dead reliable and torquey. Also it used an amount of fuel appropiate for the power it was making. The 2.25 was 75hp and the 2.6 was 90hp if I remember correctly.
I have had people trying to give unwanted 2.6's in the past to they should be relative cheap to obtain.

So you would choose the 2.25 over the 2.6...

I just seem to imagine the 2.25 struggling for power with loads on the back.

(eg 109 ute full of wood with trailer full of wood on the back?) obviously the 202 in its condition is gonna be VERY average at this task.

Obviously it will be better for matched ratios on 100k roads.

Converting the 202 back to a 2.25 or 2.6 would be relatively easy?
apart from changing the main jet?

Ive read about a "High Ratio Transfer Case" it features in the Four Wheel Drives catalouge No 33, page 20.

It mentions 'Engine RPM reduced 24% for a given Road Speed compared to original'

Would this allow me a bit more RPM for the 202 to crank up the speed?

If you are going to stay with a 6cyl motor,out of the Holden,Falcon 250 iron,and the Valiant verticle motor,the Falcon has the best torque for you, the Valiant is the lightest,and has the lower and best located water pump/fan,the Falcon conversion was popular in Victoria for years, but Illegal in QLD as was the Chrysler motor,you could always put a 200TDI in it with or without the Turbo, it will give a lot more power and should match your gearing.
