Mexican engines have cast iron crankshafts Yikes**

For christs sakes...there is nothing wrong with using a cast crank in a standard engine.This is mentioned in another thread from the other day Lee........

um i thought type 1 motors have always had cast cranks. absolutly nothing wrong with wen used for the right application. oh yeah these mexican motors run smooth as

Damn, they have cast cases too !!!!!!!!!


for shame!!!!!! :alien:alien:alien

cast rods to lol

Cast Crankshafts are nothing like cast crankcases or connecting rods or cast pistons.....

Crankshafts are Vastly different to these other items....

I'm with Pete Wood.....

I don't like them....

Remember they have been made in 3rd or 4th world country....

Volkswagen is Now Building
Golfs and Jettas in Germany for the USA market...

as they Now have a reputation for poor quality and workmanship.. and many engine problems etc

after selling Mexican built Golfs and Jettas...
or actually Rabbits and Jettas... [no golfs in the USA]

to the US....

All good, as long as you don't try and weld counterweights to one!

as for the lifters...pffft... I have to take the heads off my V6s and V8s if a lifter fails. None ever has...

havent the stock cranks always been cast? for stock applications i really dont see an issue

No - OG cranks were forged. And good quality at that.

A lot of counter weighted cranks are welded OG cranks and are better than a forged CW crank.

There are a few forged CW cranks from China that are of soft steel and a pit suspect.

That said - arent Type 4 cranks cast??

sorry my mistake. i still wouldnt hesitaste to buy a mexican motor is i was after a 1600. i have heard good things locally bout these motors

I think you will find that the cranks are cast steel not cast iron, and you would be suprised how many other make engines have cast steel cranks.

Has any one broken one of the mexican cranks yet???
I have seen a few broken Type 1 german stock cranks.

I wouldn't worry about the Mexiczn cast cranks for a stock engine.

There were cast stroker cranks around for a while, they were fine for street engines if not driven hard, I saw one brake in a 2007cc engine in a '73 Kombi after reving it past 5000rpm and side stepping the clutch.

Now you've gone and ruined all my "fun".:cry:cry

Never mind I'm sure pete will post something soon

what about in a mildly modified engine? what could one rev it to?

Holden built about 2 million straight sixes with cast cranks and mine in my EH handles 280 hp and 480 NM of torque.

I would think that unless you plan on tripling the stock hp it would not be such a serious issue.

Are type 4 cranks cast?
A mates crank snapped in 2 for no apparent reason 👎

stock horsepower for a EH is around 65bhp if I remember right so you have given it quite a push Hellbus

Yes they are cast iron. Or SG iron...what ever the technicality...but not cast steel.
Type 4s and type 1s from the old days are forged steel.
Because it is effectively a 3 main crank, it will flex in use and therefore fatigue.
The newer cast iron cranks are designed to give acceptable life in stock engines.
Modified engines will give less service life with cast crankshaft, especially with higher RPM and poor tuning.
If the crank had a main bearing supporting both sides of each big end journal, it would last well like the Holden 6 can.
...but poor tuning and exceeding design criteria is a sure path to disappointment.

Actually to be exact it is a 202 out of a HX, so stock hp is about 135hp with about 260NM of torque. 🙂

holden 6? :puke

I'm with seagull, I think you really meant Subaru. :P

Ok, I'm having too much fun, I'll stop now before everyone rains cowpoo on me. Then again...maybe not.

OK, has anybody here actually broken a crank in a Mexican motor under normal use? No I won't accept a friend of a friend stories about this or that happening.

is that a dare? 😁
