Title: Liners R18 fit R16?
Post by: Lyngeled on Sunday,May 11, 2025, 08:49:47 AM

Hello,
Anyone knows if Renault 18 1647 ccm engine liners do fit a Renault 16 (same as S2?)?

Cheers

  Richard has documented many items that can be interchangeable

  Parts are available at Renault16shop.com  they can also set you up for complete sets of pistons rings and liners.

Early liners (all original Europa engines) use paper shims under the liner to adjust liner height and seal the bottom of the liner.  Later liners used o-rings.  You can modify an early block totake later liners but it will require expert machining of the block and liners.  Not worth the triuble and expense as the proper parts are available for both applications and both applications work well if assembled properly.
