My Wife also tells me that unless a Doctor did something extremely out of line (like Murder) there is not even possible to sue for malpractice in the Philippines.

That observation is so true. You just have to choose a newer model of taxi to flag down.

And even if a doctor has "murdered" a patient, they usually get away with it.

My Wife also tells me there is a shortage of Doctors. The good ones get jobs in other countries.

I just got my car back. Thanks for all your replies. The good thing is that it does not smoke anymore at idle.

However, I noticed that it seems to accelerate slower than before. Is it possible that after replacing the chain they retimed the IP which affected my acceleration? Can I adjust the ALDA again to prep it up?

I also hear knocking on the engine at idle which I presume is from the injector and I saw some fuel leaks at the first and third injectors. Could that be the cause of the knocking sound?

Also, I just did an emission test today, which is required prior to renewing yearly registration and the car scored .69k on the opacimeter test. I don't know what the value means but it passed with 4 being the highest value allowable.

Thanks in advance on your opinions, comments, and suggestions.

It depends on what is leaking. Leaking return hoses will not cause knocking. Leaking injection line nut/injector body is a different story.
If the knocking is comming from #1 cylinder this is the delivery valve they would have had to mess with if the retimed the IP. Even when your are being careful it is easy to get dirt or other contamination in that area that will work on up to the injectors.

OT: The shortage of doctors are probably happening in rural areas. But in the city, there are a lot of good doctors. Specialists abound in every area of expertise. The best ones are already established and are here to stay since they can command a hefty fee. The good ones are probably trying their luck in other countries to further study and be a specialist and eventually come back here to establish a rewarding profession.

The non turbo is more common than the turbo which is the most desired of the diesels. So the prices tend to soar if you want to get a used turbo engine and considering they only made that engine in the US and in very rare European cases, it's not too common to have them in Manila. Even if labor is cheap the cost of the new engine offsets it so it balances out. Tough choice huh?

Anyway I hope Bong finds a solution to it. Let's wait for his reply

You are right Pat. And with a few choices, chances of getting a bad engine is high. A total rebuild would cost about $1,500 including labor and you are sure that everything inside is good.

Pat, would a surplus 617 turbo fit in a Balikbayan box?

Bong I guess at this point it's safe to say there probably wasn't anything wrong - everything was done right - but maybe the timing chain was just at the point of breaking and it was just the right time for it to go. Sadly that equates to being the wrong time for it to break for you.

How many miles does your car have?

I am also leaning to that conclusion that they did everything right except for the advice to retain the chain.

I don't know what is the real milage of the car but the condition is it has a little blowby, starts great, is powerful enough to do 60mph in 20 secs. since the turbo was fixed, and goes 24mpg. The valve adjustment should have made an improvement on 0-60 and suddenly... something snapped!

Oh well, I'm going to the shop later and find out how she's doing.

MBeige · #10 04-23-2008, 03:40 AM

Bong, check your PM

MBeige · #11 04-23-2008, 03:50 AM

60mph in 20 seconds sounds too long. Hopefully once you get the top overhaul done it'll be closer to 15. I remember that turbo problem you had too. 24mpg is very good for conditions back there!

Keep us updated!

So, if you paid an anesthesiologist...
hmmm

Sounds like trouble.

MBeige · #13 04-28-2008, 05:37 PM

Bong, can you tell us what was done?

The anesthesiologist may be of help in dealing with the bill...

Camshaft, camshaft bearing, railings, sprocket, tensioner, and chain was replaced. Oil changed with pan removed. I have not seen the complete bill yet since they delivered it to me so I can test it out.

What I noticed is it feels sluggish on take off. 1st injector nut is leaking maybe causing the knocking. I also feel that fuel economy dropped as my needle drops faster. I know because this is my daily driver.

I also noticed that smoke is gone when idling. Could be because they also retimed the ip. Can I adjust the ALDA to perk it up again?

Back off/loosen the injector line nut and see if the threads have been cross threaded. Look at the cone shaped tip of the injector line and the reverse cone where it fits into the injector and see if they were damaged or something got pinned under them when they were tightened down.
You can loose alot of fuel from a tiny fuel leak.
