MB100, Ssangyong/Daewoo Istana [ARCHIVED]

**wax** · June 22nd, 2005 04:56 PM

My MB100 already have 86K on its odo. It is a 97 Ssangyong unit but was brand new when imported last 97. I got it for only over a year now.

Maybe I'll just do that. I can take out my DVD and my 2DIN stereo muna (I changed the original Ssangyong). Anyway, it's not that hard to take if off and I can just install it back myself when it's done.

Still, I can talk to Mang Rudy that he'll guarantee my van's safety.

the price is a little high, pero that's just my opinion...no experience with the mb100 engines.

pero why don't you ask around muna kung magkano per piece ng lahat ng piesa na gagamitin? new liners, piston rings...the whole overhaul kit for your engine. add 20% for the machine shop, 10% for new oil, filters, maybe an injector clean and the rest will be for labor. if they'll be charging more than 20T for labor alone, hmm, medjo mahal.

volts ..

actually ang charge nila for the labor is P12K. I think the next thing na mahal is the machine shop. How much normally should they charge for a machine shop work? I remember Mang Rudy estimated around 10K for the machine shop alone. Medyo natataasan nga ako e.

I will ask them for a parts list for this project so that I can compare around.

Thanks!

All you have is verbal guarantee for the safety of your van even it's out on the street. Suggest that you look for a safer shop with equivalent expertise and cost so you can have peace of mind while your van is being repaired.

geebunny ..

actually i really don't feel at ease leaving my van out on the street maski sabihin nila na secured yung place nila.

i will shop around and compare their prices. i will try to look for RBL again. di ko kasi makita the last time i tried.

during late 90's kumatok din yung engine ng MB100 ng brother ko, he was able to get CASA replace the engine after proving that the cause was ingested water from a small puddle during rainy season in Manila. Problem is air-intake of the MB100 is pointed down so it's really prone to suck even water... good luck.

For 39K to 40K that is quite expensive and the problem with overhauling her is that the machine shop does not do good work. Try shoping around for a surplus engine it might cost half the price and faster to work on. I just had my cylinder head overhauled last year of my sentra diesel. This year it overheated again when I had it checked the machine shop resurface it too rough. I spend 15k for the overhaul head I just bought a surplus head for 7.5k and now its ok working na without overheating for 5 months. When you buy a used engine they ussually test run it just bring a qualified mechanic to check it and make sure they have papers when they sell you the engine.

My MB100 unit is a Ssangyong and yes the air intake is pointing downwards. I am planning to replace it with the new intake and weather strips on the hood.

I asked around this morning to compare the prices. MCR is replacing all my piston rings with Germany parts. That's 5 sets since MB100 is 5 cylinders. Other shops only use Korean brand parts. At least that's the guarantee I got from Mang Rudy. All the parts that we'll use Germany brands and is really of good quality and he'll only replace parts that really needs replacing.

He'll take care of the machine shop. He knows better where to bring it since their shop specializes in Mercs.

I am scheduled to bring in my unit tomorrow so they can start with the repair. It will take 4 to 5 days to complete the job.

teka...piston rings lang?

a full general overhaul should include new liners (piston sleeves) for the cylinders. usually yung original cylinders have ridges around them na, so the piston mating to the cylinder is not 100% tight. this the reason for blow-by - gases escape through the gap between the cylinder and piston.

kung walang liners, at new piston rings lang, they might go for oversized rings to compensate for the wear of the original cylinder. hahabulin nila yung seal, ika-nga. kung ganito, you might as well say "dukut" na lang (change piston rings, cheaper ng 70% sa overhaul). dati yung pajero ko pinadukot ko yung rings, 5T lang ang singil, all-in. that was 2 years ago.

think about it...if they will just bore the cylinder block (to remove the ridges from wear and tear) then install bigger rings to ensure a tight seal, all without installing sleeves (to bring the size back to regulation size), pretty soon wasak na ang rings nyan. the dukot system doesn't work, or doesn't last. if they'll bore out the block they must use new liners.

insist on seeing all the required parts before you pay. ask if they will re-sleeve the block after the machine shop part. if not, well, it's up to you kung i-ririsk mo na gumamit ng oversized rings.

tsaka sa presyo na yun dapat kasama na lahat, pati oil, filters, calibration. 50T is not a small sum. overhaul ng 4d56T ko nun cost 20T lang daw e, all in (accdg to my pinsan who used to own it). given na 5 pistons mo at medjo exotic, 50T is still the going rate for a surplus 4m40T (pajero engine 2.8T).\

lastly, wag ka masyado maniwala jan sa germany ek-ek stuff nila. unless you see "made in germany" stamped on the metal parts, haggle some more. maraming kalokohan sa diesel engine repair, trust me, i know. they won't be fabricating new engine parts from scratch (ala-Rides sa discovery channel), so you're entitled to haggle their ass off gawa ng baklas kabit lang naman gagawin nila.

Hi Volt ..

Thank you for your advices.

I only mentioned piston ring because that is one of the many parts that I compared with the other shops. They're not doing dukut. We will also be replacing or using the sleeves, bearings, seals, kits, etc. According to MCR, there is no oversized piston rings for MB100. If ever there are, we are not doing oversized rings. They'll bring it back to standard that is why we are using the sleeves.

Honestly, I am not really that familiar with diesel engines that is why I am trying to get more information from this forum to help me out.

I went to MCR because it was one of the shops highly recommended by some of the tsikoteers. As for the price, the 40K is just a rough estimate. It might go down depending really on the damage and the parts that we'll use. One thing Mang Rudy assured me, that he will only recommend changing the parts that really needs changing. Kung okay pa naman daw, they won't replace it.

I tried looking around before for a surplus engine of an MB100. The cheapest one I saw was 60K. I was thinking kasi before that I might end up with the same problem if I get a surplus engine that is why I just opted to have it overhauled.

I will ask to show me the parts before they start working on my van. I will also try to be there on my free time to see how they work.

I am really hoping that everything will work out fine, for me and my van. Yes 40K is no easy money. I already talked to Mang Rudy and told him my feelings about the cost and he promised to help me out.

I'll just pray for all the hands that will work on my van ...

Thanks again Volt!
