Commercial's 4y

[Jaco Versfeld]

I just popped in Commercial. See they have new stock - I had quite a scare the other day when the floor was empty ...

New 4YPs are R500 cheaper than what I bought mine for. :evil:

Mine is still going strong at approx 2000 kms, just very thirsty at this stage :roll:

Hi Jaco
How much do they go for now? I'm considering it...

[Jaco Versfeld]

The 4YP (partial - only sump, block and top(??)) is going for R5500, the 4Y (with alternator, fan, starter, carb, etc) is going for R8950.

[Hannes.S]

W00t!!!
That's cheap
I have to replace my head (head on 4y I mean) when I removed the head the first time, I saw the previous owner replaced only the number 4 piston. And thats not something I like. If you have to work on one, U might aswell do all of them.
So its either, replace head and do all the pistons or go commercial.

That's good to hear :!:

Cape Town was empty last time I visited

My 4YP is just clocking up 15,000kms; hasn't used 1 drop of oil and is going like a Boeing

Help 'n bietjie asb . Is dit 'n nuwe nuwe enjin en 'n egte Toyota of hoe werk dit ?

[Jaco Versfeld]

Hi Arno,

Dit is 'n nuwe engin (jy moet hom inry), maar dit is 'n generiese (Chinese) engin. Die kwaliteit is baie beter as die ander - Commercial het glo probleme met die Taxi Association gehad met ander engines.

Dit is 'n 4y, so teoreties "drop" jy hom in die oue se plek. Die mechanic wat myne gedoen het, het wel 'n challenge gehad met die manifolds.

Toyota vra omtrent R20 000 vir 'n 4y. 'n 4y hou seker so 400 000 km. As die Chinese een 200 000 km hou, werk dit my nog goedkoper uit (met instellasie in ag geneem) ...

Die parte ou by Brenners Toyota spot my oor die engin, maar ek kan dit handle

[Hannes.S]

Ek is gou besig om pryse tekry vir my std 4y.
Ek beplan om die engine oortedoen, want ek raak nou keelvol vir die gesukkel. Ek Kon nog nie regtig die gevoel kry van die EFI converstion nie, omrede my engine loop en mis heeltyd.

Ek het nog nooit n groot "overall" gedoen nie maar daar is altyd n eerste keer

Het ek iets gemis op my lysie?

1: 4x Pistons en Ringe
2: Big-end bearings
3: Full gasket set (sal payen werk op toyota)
4: Olie pomp
5: Engineering (blok en head)
6: Bietjie Koffie
7: Baie geduld


Die rede hoekom ek alles wil doen is. Ek het n headgasket geblaas op die engine, en na ek dit reg gemaak het, het hy net bly loop en mis. Dit kan nou of die head wees of dit kan die no. 4 piston wees wat seer gekry het?

Wanneer laas het jy 'n waterpomp vervang? My Pa het my geleer as jy die enjin oordoen doen jy alles, waterpomp en oliepomp ingesluit.

Hoe lyk jou clutch en pressure plate? Terwyl die enjin uit is is dit dalk goed om dit ook sommer te doen terwyl jy besig is.

Ek dink nie Dit is al ooit vervang nie! Het so bietjie vergeet van die waterpomp
Die vorige eienaar het nie baie moeite gedoen met die lux nie. (seker 'n ex LR eienaar)
Sal gou waterpomp en clutch by my lysie sit.

[Hannes.S]

Ek het nou gelees jy kan jou ringe se kompresie toets deur n bietjie olie in jou vonkprop gat in tegooi.
En as die kompresie styg met die olie in, dan is jou ringe op-pe-la-las.

Hoeveel olie dink julle moet ek gebruik, kan seker nie teveel wees nie?

[pietpetoors]

Ek het dit nog nie gedoen nie, maar ek sou vermoed dit is net om hom te seel, so so 50ml sal seker genoeg wees as ek moet skat.

Somehow I don't like this idea... 50ml sounds like alot!

Hannes, have the flywheel skimmed, if u are going to all the effort of a rebuild, have the parts balanced before assembly, a standard 4Y is a pretty unbalanced machine, they benefit from balancing quite a bit! Then while the engine is out, check the condition of the spigot shaft seal on the gearbox, if there are any signs of leaking/sweating, replace it... it's pretty cheap for the orginal from Toy .. while replacing make sure you put the new one in the right way around(like the one in place now)... I've made that mistake once before... buy and install an original Toy rear main seal(and crank shaft seal), the pirate ones very often don't last more than 1500km... and if the pirate one goes then you going to have to pull the motor again!(again I've been there done that... learnt my lesson)

And if you buy a gasket set make sure it is Payen

[Family_Dog]

In all honesty, I think it would work out cheaper to buy a new Commercial 4Y engine. Remember, the head will probably be re-skimmed again and the block re-bored. Once you've done all this and fitted new bearings, pistons, rings, oil pump, water pump, gasket set (Payen is excellent), valve seats etc you're not too far from a new engine's price anyhow. It actually cost me R1000 more to re-con my original 4Y than a brand new Korean 4Y cost at the time. In the end though, I ended up fitting the new 4Y and also rebuilding the original engine as well.

Or buy my Jap 4y and send it to Allan for some TLC...

My 2y 1.8 engine het op 378000 sy agterste piston skirt gebreek toe dog ek dis die valve lifters wat raas, toe sit ek nuwes in en toe maak hy nog steeds die klap geluid en toe doen ek n toets duer die sparkplug drade 1 vir 1 uit tetrek as jy die vuur af haal dan is die kla klap klap geluid weg toe kom ons agter die piston het gebreuk. Dit lyk my dis die y series se probleem daai, ek het voorheen by n ingineering plek gewerk toe het daar ok n' 4y aan gekom wat se piston no 4 gebreek het.Maar die y series is goeie engins uit my ervaring uit.
