I install Bar head gasket sealant in my motor due to blown head gasket! Decided to try this due to the motor over heating 6 times and having a rattle on cold start up! I decided to do a combustion test which showed that we have a blown head gasket which was causing the 4Runner to idle bad and not drive at all due to engine overheating in 10 mins! So with the motor rattling I decided why not try bar head gasket sealer and so far it has worked!
After doing the bar seal we did another test and no combustion leak also the check engine light went away and the 4Runner idles to where you can’t feel the 4Runner running! So if your in a bind and need a fix this will get you by not sure how long but I’ve put 400 miles so far no issues! #ledheadlights #raptorliner #barheadhasket
