Daihatsu Copen Engine Rebuild

I don?t know what your issues are friend, earlier you thought the head is unusable, destined to be scrapped. We were able to use the same head. Then you had a point of view if it is used it will give horrendous unimaginable knocks, while standing at the back of the car I witnessed nice pristine exhaust note. Then it was with the engine break-in stuff. I told you there is not just one correct way but multiple correct ways of doing it. Hell if one is good at one?s work, one can develop its own correct way of engine break-in routine and sell it in his business model as a USP. For you besides good power output, noiseless engine, a fuel efficient engine is not a success yardstick; then one wonders why people are getting hooked to hybrids. People are better off with a horse cart, it will give one horse power and unlimited efficiency with all good handling characteristics if time is not money. Now you want me to give you owner manuals with driving instructions. As far as engine life goes; you are here, I am here and the engine is going nowhere either. We shall see in few years? time whether our practical or your theory turns out to be correct. If we fail, don?t worry we will give our money back to the client as we invested in it even before he did and will send you the pic of it too.
It is sad to see that this thread is coming to this point where as it was started with good intentions. Don?t be offended; if you want to know/ learn what we did with the head, the cylinders, the pistons, the engine break-in and stuff and the tricks up our sleeve, it will not be for free, apprenticeship is the way. Else let us do our job as we know our craft.

In international communications - this is called "being Pakistani" - technician skill is warped into craft with secret formulas - that too on old Japanese engines lol. - kaam ki baat nahi karnee, aur afsanay batanay hain.

lol

Yar aap se bus akhri baat ker raha hon. Apni kull theory aur meray afsanay bamaa tasweeron kay, kissi KAAM wale ke paas le ker jao aur uss ke saath beth ker sar joro aur pocho ke ustaad yeh iss banday ne kya jugaar lagai hai. Aur bhai engine naya ho ya purana, ghoroon main dum hona chaheyay.

lol - umm - I have worked in prototype development of such stuff - I dont need an ustaad to sort it out for me. My degree also helps me understand such better.

cratered head - causes preignition, grinding it increases combustion chamber volume, welding it will warp the head, even when welding such you need a 4047 welding rod and good knowhow of what you are doing - a porous job is worse than the original fault you started with.

Do share with us your facility that uses 4047 rod with an argon shield to weld this up.

a simple question was asked to which I got a fairy tale telling me to go to some imaginary ustaad to ask how this worked - I already know how to repair such - its basic common knowledge (elementary) when working on such machinery. Problem is - its cost prohibitive to do that on this cylinder head.

ghoron mein dum to hona chahiye - bilkul, yahan ghora nahi chooha hai

Yar aap ko jaan ker ab haqeqat main bari khushi hui. Itna waqt le liya shanasai main. hamara to ghareeb khana hai bhai. Lahore main ho to millo to sahee. Chai bhi piyenge aur afsane bhi share keringe. waisay jitna ilm hai uske baad itna to bata do keh yeh engine kitne dinoon main farigh ho jaeyga???

I Am OUT....! Not Getting Any Decent Answers and Backing Of What Was Claimed....! Useless To Argue

I believe that rotten fish do not need an expiry date. The question in the post may better be replied by:

Xulfiqar never claimed to be future teller.

Is it over? Or should i get myself popcorns nd a drink.?

Why don't you do a simple compression test on your customer's car? We will be glad to see the results.

It's like the war between foreign jugaar

Vs local jugaar

They both work [emoji14]

I suggest to Op that it's better to know to whom he was discussing. What are their back ground. Xulfiqar and senior gtr both are very respectable members of this forum. May be you have done a marvellous job (on the basis of your secret business traits ) , but what they are asking is pretty basic. And a healthy discussion may be fruitful and intresting for people like me.
(By the way I have finished my first bucket of pop corns) :D:cool:
