Hello Everyone,
I hope I didn't mess up. I went and looked at a car I didn't need or particularly want. And yes, I bought it. A MK2 Golf. The ad said 1.9 tdi. I didn't know what I was looking at since the only engine/s I studied was/were MK1 1.5na and 1.6na.
So, the son said the father (deceased 2001) ordered the block from California from a Passat. He said it was an ALH block. It looks like some kind of similar conversion of what is being sold on eBay (
http://www.ebay.com/itm/VW-Volkswagen-1-9D-LONG-BLOCK-ENGINE-with-1-5-1-6-to-1-9-UPGRADE-KIT-/171529128211). Eventually, I was told it was a 1.9 block (confirmed the block stamp is really a 1.9D not TD) with the original 1.6TD head and components bolted on including some modifications. Assuming this is true, then I have questions:
--What is this block? Block stamp 1.9D below exhaust and this is the number from below #3 and #4 (20J93). If this is enough to ID, is there a database to resource?
—Motor observations. The block should have <40Kmiles on it while the head and other transferables will have something around 125Kmiles. The motor seems tight after 3000rpm. The turbo is barely audible. No obvious whistling or spooling sound, but it’s there for sure. Sweet spot is 3000rpm (~65mph) in 4th. Does that sound about right?
--Is this setup ok? and reliable? I want to drive 90 miles a day, every day; nothing fancy; good mpg (+40), and not get run over.
--Oil capacity. What should I know? It has an oil cooler. Does it need a deeper pan if it is the original 1.6 pan? Frankly, I have no idea if this matters. I read 4.5l (4.8Q) for 1.9TDI?
--Injection pump. What is this? 1.6 or 1.9 pump? and does it matter? The son said the father took it to a diesel shop (not a VW shop) to do something about it starving fuel to motor.
—Turbo. How/Where to ID the turbo?
--Transmission. The numbers were scratched off. Does this matter? Also, the speedo cable looks like this on the tranny end and the other end is some kind of sensor sensing a magnet epoxied to the axle. Do I need to put a legit cable back in?
The water temp gauge hardly moves. I plan on putting a mechanical gauge shortly. That terrifies me.
What are some observable differences between the 1.6D and 1.9D. Can you recommend some specific items I need to read up on to be a responsible TD owner/operator?
That's all I can think of at this moment. I am sure I am not done questioning the purchase or my sanity. Thank you everyone.
