Back story...
three months ago
start home and five mins into the drive temp gauge is sky high. Refilled rad. with some water and I limped home with the keeping the temp gauge happy by keeping the rpms around 3k. My heat was my canary in the cave, it would cut out if my rpms were to low. I guess the water pump had some air cavitation.
paid a duty dealership mechanic to replace the HG, timing belt, water pump
Engine had a ticking sound, especially when cold around 2k-3k. Thought is was a piston slap.
Over the last week I ran it the engine would die at a stop and that last time home ran real rough. Thought it might be my tensioner.
I replaced the tensioner, pulleys and a new timing belt. I do think that tensioner had to be replaced, because the sound I heard on other videos about tensioner is gone, and the car does not die with the diving RPM's like it did before.
But now the engine has a very loud sound. Is it a loud piston slap and I should just ride it out?
Here's a link to hear the engine, at ten secs in you hear the louder sound I'm concerned about.
thanks
If it is piston slap, do you recommend marvel mystery oil? I just switched to sythentic the last oil change….?
