The engine in this Z24 is the LD9 with the 8th VIN digit the letter T.
Most engines in these are indicated by either the number 4 or the letter F as the 8th digit. I need to know which is the correct oil filter (Fram, for example) for my LD4. I have read that this engine uses a slightly different oil filter than the "4"'s and "F's". I have a possible oil leak issue I am addressing, which could be from the oil filter seal. The current filter is: Service Pro M4006. This was on the car when I first purchased it 700 miles ago and there were no leaks until very recently. It also sounds like there may be a loose timing chain issue developing. Before I go in and look at the chain guides and tensioner and effect necessary repairs if needed, I want to be sure the filter is not part of the problem.
And yes, it does have that 2 second timing chain rattle when you first start the engine, but this rattle now seems to be starting to occur when engine is warmed up. (Could also be valve train.) Unfortunately for me, the LD4's timing chain tensioner cannot be adjusted/replaced without opening the timing chain area. I have been researching and finding different opinions on which oil filter is the correct one, so I've decided to ask the only people who would really know -- 2CarPros. You people rock!
Happy Holidays y'all. I almost forgot, this has a 5-speed manual and is a coupe.
Another question, how can I tell which of the 2 manual transmissions are in it. A VIN check doesn't tell me. VIN 1G1JH12T627132189. Thanks.

Hi,

As far as the engine oil filter for this engine, I attached a pic below with the OEM part number from GM. You will need to cross reference that number. However, if you type in GM part number 88984215, you can purchase the OEM filter.

As far as the transmission is concerned, that is a little more confusing. You need to know which engine, which you included above. From that, you can either check the RPO number or I found a breakdown by the engine. The LD9 engine used the M5 (5-speed) Getrag manual transmission. See pics below.

Let me know if this helps.

Take care,

joe

Thanks for the super quick reply. I will source the filter with your info. The other choice of transmission has the word "Opel" in it. I was hoping the transmission is the one you came up with, as they have good products.
Great job and a tip-o-the-hat to you!
