Advice On How To Avoid Issues When Replacing A Chain
On 3.8 (380) V8 engines from 1980 to 1982 with a single row timing chain, this kit will not fit. Twin row chains are to several of these vintage engines. Remove one valve cover and inspect if you are unsure before opening it!
The oiler tube clamps and the valve cover gaskets are not included in this package. The clips are plastic, and they should be replaced if they haven’t been in the last ten years (or your camshafts could be ruined). If your clips have been replaced, we do sell a valve cover gasket set individually or a valve cover gasket set with clips. In the end, it could be a good idea to change your spark plugs at the same time because you will need to remove them to replace the timing chain.
