Ok so i got this 86 rx7 non turbo. its a missile but its been a damn good one up until recently. so what happened is a radiator hose blewout on the highway and the engine overheated right after. since then ive replaced spark plugs, thermostat and a radiator cap and radiator hose. kinda been hoping to be lucky enough to avoid a rebuild. any how as of right now its reluctant to start, and when it does it smokes (what i think is oil) like a damn factory. itll run ok other than the smoke but wont start again for a while. plus the antifreeze likes to boil over some without actually getting hot. am i safe just replacing the oil and antifreeze or am i in or a rebuild and if so which kit would you guys recommend

 

Sounds like you have damaged water seals and need a rebuild

 

thanks rebuild kit just arrived today
