I take a moment to show you how important it is to always make sure you are on the right track with your diagnosis. It's easy to assume especially with a pattern failures. Only take a minute or two to be sure you are 100%

Eric O is consistently a RockStar diagnostics engineer. I'm always impressed, and that isn't easy to do having spun wrenches and diagnosed a fair bit of my life, cars and data centers. I'm an IT nerd for a living and a backyard wrench spinner out of irritation with poor auto shop performance. Grew up working on cars with my dad at 9 years young, and outside of dealer recalls(esp on the wife's car, its a VW. but I drive the ultimate parts machine, a BMW), do all the work myself.

Yeah I thought I had either a cracked head or leaky head gasket. Before going for parts I thought I d better take the heads off and at least look at them. When I got it apart I realized a head gasket wasn t gonna fix this problem. The block had a big smile in it. A crack about 2 inches long in the shape of a smile. So it pays to look a little deeper like Mr. O did. It can save ya time and maybe a little embarrassment in the long run.

Good call on the double take. Have done similar misdiagnosis on a buick 3800 (in a holden though) hairline fracture in head causing high pressure in cooling system, thought it was the falible inlet manifold gaskets: / second hand heads were 40 bucks each. New inlet mani gasket 60 bucks. Massive headache averted.

You totally missed an opportunity to make more money here. You could have 'fixed' the issue (like maybe seal the crack with a temporary sealant) then once it starts acting up again you get to 'fix' it again, or even fix it for real. Make more money that way.

See, this here is why you're the professional mechanic and I just pretend to be a mechanic on the weekends when my own vehicles are busted. I'd have put an intake manifold in it and been quite pleased with myself until I found out the problem hadn't gone away.

WOW Eric, you never seem to let me down. What a great save, an embarrassment to say the least and I don't think anyone would believe you after you changed the gasket and than came back and said, OH I found the problem, after the statement!

The manifold cracked when the old engine was replaced with the new-old engine. Probably over-torqued the manifold with the hoist. Small crack became larger over time. Should have installed a new engine to avoid future problems.

Soapy water is the same as spit. but the spit is very low.
In other words, you can use spit on valves to see if they leak or not. learned that in my HVAC clases. and also learned that some peoples mouth stinks like skunks

Love your videos, honest work, and you bring honor to your craft. So many dishonest mechanics out there. You sir do your homework and make sure you do the job right to the best of your ability. My hats off to you

That engine is probably from a wrecked car and no one payed the attention to the possibility that the manifold took a hit, and I think you are only guy stubborn enough to find it, great work Eric
