Ok the chain on my car is a single or (simpelx) chain the chain the had given me was a double or (duplex) chain... does this mean i have a diffrent vr6 engine coudl it be a golf engine 2.8ltr and not a corrado2.9ltr.. even though the engine came out of a corrado shell! does anyone know why there is a diffrence here?ggaarr :cry: Thanks Joel Link to post Share on other sites

ingham 5 Posted August 7, 2006 Report Share Posted August 7, 2006 The later engines had a top simplex chain with differant top tentioner blade and tention bolt and is better design Link to post Share on other sites
NWGRE38 0 Posted August 7, 2006 Report Share Posted August 7, 2006 Golf engines changed to a top simplex chain after engine no. AAA217001. I think this also marked the change to OBD II diagnostics. There is an OBD guide on vr6oc site.You should be able to get an idea from this what sort of engine you have. Good luckNick Link to post Share on other sites
antera309 3 Posted August 7, 2006 Report Share Posted August 7, 2006 The bottom chain, tensioner & runner are the same on all VR6s. The top chain, tensioner, tensioner bolt and guide are specific to OBD1/OBD2. OBD1 has a doube-row chain, OBD2 has a single row one.All corrado 2.9 engines are OBD1 and should have the double-row chain. Link to post Share on other sites
The Punisher 0 Posted August 8, 2006 Author Report Share Posted August 8, 2006 this definatly has a single chain so your saying its an OBD2 engine... must be the diffrent engine in the car J Link to post Share on other sites
antera309 3 Posted August 8, 2006 Report Share Posted August 8, 2006 I can tell you for sure if you can give me the engine number off it. It's stamped on the engine block at the belt end, just below where the head joins the block. Link to post Share on other sites
