Graham Posted March 15, 2022 Report Share Posted March 15, 2022 Am I correct in thinking that early cars TR5’s and early TR6’s had screw in injectors and latter cars had push in ? Quote Link to post Share on other sites
BlueTR3A-5EKT Posted March 15, 2022 Report Share Posted March 15, 2022 Screw and push refers to the way the plastic insulator fits to the injector body. They are all fitted into the manifold by an 'O' ring on the nylon insulator, the injectors and retained in the manifolds in pairs by steel retainers each held by a screw.

That just refers to the surrounding insulator, they still have retainer plates. Stuart. Quote Link to post Share on other sites
Steves_TR6 Posted March 18, 2022 Report Share Posted March 18, 2022 The three PI cars ive worked on all had a mix-n-match set of injectors! Neil Ferguson supplied matched sets of push in refurbished injectors and additional plastic holders to complete the sets. it’s 9 years since these were fitted to my ‘6 and it’s still running great, if a bit leaky now in the oil department ! steve Quote Link to post Share on other sites
