carbon lock...

confirm wrong usage of oil...... nthing to do wit redline,, infact, i wld tink redline no enuf, which makes it worse....

some of the guys who have their engines busted (other than those who FI and failed) in spore will attest to the pictures above...

 

Ouch!! Good luck with the replacement csl.

 

is trust rotary oil 10w-40 good for 4AT?

 

so long as its rotary oil, it shall do fine.

 

thanks for advice...........

 

csl bro,

sakit to see the pic man. what engine oil u use?

Good luck with the rebuild.

 

Using trust 10w40 re spec. 2k km also never needed to add oil (and the oil is clean). I think the carbon thing was build up during I drove the car to sunway after blown. But not too sure. I think I ain't gonna rebuild. Most likely buy a complete new engine. Cuz the block also got a bit bent. Cost for all parts almost the same, may as well once and for all. If anyone knows there is a place can rebuild this condition of engine for less than RM10k, kindly please let me know.

 

carbon lock is not built up over only 2000kms.. most prob is inherited from previous owner

 

we use the same engine oil, dont scare me brother.

 

New engine estimated 18k..... If you come across used one will be 8k..... But it's advisable to use new housing for longer lifetime.....

 

Used one may end up with blowing up sonner. But no doubt the price is very attractive.

 

Time to post my busted rotor upz liao !!!!!! hahaha

Compared to the above pics, I tink my rotors are worse than that !!! Even my housing weren't spared !

 

Check your PM

 

I do noe ppl in J.B doing engine rebuilding,but not very sure is he exprience in 13b and any after effects,ask coupe07 wat to do to save u if nt pm me i will try to get his no. for u.

 

indeed its from the previous owner. no doubt. trust oil is good. bro the carbon build up cannot be a few days work.

 

is yours confirmed to be because of oil or other reasons?

 

Definitely oil issue !

 

so how did u bust your rotor mate?
pls share...

 

Carbon lock.... hmmm.

Premix will help to prevent??

 

With the help of Wangan, I chose to send the remaining parts which are reusable to Autoexe for rebuilt. Price slightly more expensive than the new engine. But may able to resist more punishment . But will watch out the red line and maybe try the fuel premix deal.

Really wanna know the root cause of the thick carbon. And don't know if add those fuel additive (cleaner) will spoil the seals or not.

 

How good is the engine really depends on how engine was run in..... This was told by RX7 owners....... Did Autoexe say wat particular apex seal are they gonna used??? So far i haven't found any strenghten aftermarket apex seal.....

But if you still drive the way you are, i don't see it go pass 20,000km.......

 

This lesson not cheap. Sure I'll drive less aggresive :D . Don't know what they are going to use. Most probably original. If race prepare sure will cost at lease 10x of the current price on the engine alone.

 

heres my scenario.
1.car shakes at idol pretty noticeably and always has from what I remember.
2. cel came on about 1000 miles ago. mazda replaced plugs and coils
3. oil light came on yesterday checked oil and it was kinda milky. (maybe from cold cold illinois winter?)
4.i noticed oil under my air box when I was in there.
car has 37k miles and is all stock. seems to start up and run fine. any thoughts???
