TIM­ING CHAIN TROU­BLE

Classic Car Weekly (UK) - - BUYING & SELLING -

Don’t worry about worn Nikasil cylin­der bores now as well­main­tained en­gines man­age 200k miles plus. More im­por­tant is tim­ing chain and ten­sioner re­place­ment – early plas­tic ten­sion­ers were frag­ile and were re­placed with steel items – and if the chain lets go it’ll take the en­gine with it, so bud­get £1000 for a spe­cial­ist to re­new every­thing. Smoke or signs of com­pro­mised head gas­kets are an ex­pen­sive worry, so look for oil and wa­ter mix­ing and get a com­pres­sion test done if you’re un­sure.
