This is a 2002 Pontiac Firebird with the GM 3.8l 3800 Series II Engine. This vehicle came in with an large oil leak on the engine and an oily substance in the radiator. The antifreeze was mixing with engine oil. The problem is common with this series of engine. The lower intake manifold gaskets deteriorate and case coolant to leak into the engine oil, oil is also allowed to contaminate the cooling system resulting in the fouled coolant and soft radiator hoses. This is multi part repair and is somewhat difficult in this particular car due the firewall and wiper cowl location. We will remove the intake plenum and lower manifold valve covers, and the engine accessories such as alternator, belt, and the tensioner. In this case the belt tensioner also has a heater core bypass built into it so there is engine coolant in the belt tensioner as well. Part one will be the teardown, part two will be engine assembly and the final part will miscellaneous assembly, fluids, cleaning and final inspection. This video is part two of this series. As mentioned in the video this vehicle was featured before due to catastrophic A/C system failure. See links below for all past A/C videos.

    I am 3 days behind. Need to do a Rays show binge…. need a cold beer or an old fashion drink.

  2. Avataaar/Circle Created with python_avatars @fsurulz says:

    Ray u r correct.. u can't make everyone happy- just be sure to make the Wife happy.. 😅 because she knows where u work 😂

  3. Avataaar/Circle Created with python_avatars @TairnKA says:

    Yes, for me, under 45 minutes (closer to 40) is good. 😉

    Hi Ray-I’ve been meaning to ask you about your experience with brake clean. Have you ever had an issue with brake cleaner reacting with different plastics under the hood?

    I was using brake cleaner to clean out old grease from a bearing slide set, and some got on a 20v battery and the charger for it nearby and it immediately reacted and started melting the plastic on both where it splashed and the smell of melting plastic was awful.

    Just curious if you’ve ever had that happen. Love your videos! Fan from the beginning.

  5. Avataaar/Circle Created with python_avatars @jimmycheese3817 says:

    I love the new Burt Bacharach music in the background.

  6. Avataaar/Circle Created with python_avatars @jimmycheese3817 says:

    Are the new manifold gaskets any more improved or heavy duty to the original ones? It seems like typical failure point and easy street creed for a company to improve on them (looking at you Felpro).

  7. Avataaar/Circle Created with python_avatars @davidtappe5337 says:

    Are you playing this music in your shop? It is killing me. Stop the madness.

  8. Avataaar/Circle Created with python_avatars @trevornelson7524 says:

    Heh the new background music is makin me sleepy 🙂

  9. Avataaar/Circle Created with python_avatars @higginsdesigns says:

    Feels like someone is playing Minecraft in the back.

    Love your content Ray!!!

    As Boss Ros is to master painter

    You

    Ray is master technician!!!

  11. Avataaar/Circle Created with python_avatars @gasselectric says:

    Great video

  12. Avataaar/Circle Created with python_avatars @Garand1340 says:

    Great video Ray. So many snowflakes crying about the music so don't stop using it.

  13. Avataaar/Circle Created with python_avatars @ShoreBoyzProductionz says:

    I know I’m late to the party, but that Darth Vader “good” after cleaning made me think that he should use a lightsaber sound when he takes the break clean can out. I know he used to use a sound for it already. Just a thought though

  14. Avataaar/Circle Created with python_avatars @frankhinderson9100 says:

    Please please go back to your old way of editing your videos.

  15. Avataaar/Circle Created with python_avatars @steveydent says:

    As everybody else said, please quit with the music ray. put the shop radio back on.

  16. Avataaar/Circle Created with python_avatars @swolenation8432 says:

    Nevermind I eat my own words u did lube the valley I hadn't watched that much of it yet

  17. Avataaar/Circle Created with python_avatars @swolenation8432 says:

    I would do the same exact thing as you but just spray that engine valley lifters and pushrods with some of the engine oil after its all super dry with the brake cleaner then wipe the gasket surface off one more time so that when it starts first time she's lubed right up. Might not matter though idk just a thought

  18. Avataaar/Circle Created with python_avatars @mrs323 says:

    I wonder if the music is there to ease up on content warnings when the mic picks up the radio playing copyrighted music.

  19. Avataaar/Circle Created with python_avatars @ghazwanh4259 says:

    i can see that you have a working parts washer machine (finally)
    hoo hoo🎉 😂

  20. Avataaar/Circle Created with python_avatars @shannon-852 says:

    Rays been working on his camera skills today, getting good at that!
    The meditation music is also a change from the normal, hope no unhappy customers are causing you additional stress my man.

  21. Avataaar/Circle Created with python_avatars @markharris7662 says:

    I do love the brake clean shout ANOTHER. Then the throw across the workshop floor.

  22. Avataaar/Circle Created with python_avatars @spazmotorsports9128 says:

    Interesting choice of background music……way too soothing🤣 thought I was watching my dentist work on his car😜😁

  23. Avataaar/Circle Created with python_avatars @ericoverholt2693 says:

    Like the 2x speed up of bolt tightening, etc. Plus, the Alvin and the Chimpmunk imitations are fun too.

  24. Avataaar/Circle Created with python_avatars @dublindave5795 says:

    What is the rubber strip for that is on the front and rear intake gasket? it looks like its just hanging out in the breeze.

  25. Avataaar/Circle Created with python_avatars @pokefan5022 says:

    You should have gone 100% Bob Ross on this one. The calm piano in the background, the soft whispers, you should have called it a Happy little gasket. Then described how it doesn’t like being alone so you add a happy dot of sealant.

  26. Avataaar/Circle Created with python_avatars @surferdude4487 says:

    Did someone make a claim on your videos because of the popular music playing on the radio?
    That leaking gasket made a mess. Are you sure that the bottom end of that engine still has bearings?

  27. Avataaar/Circle Created with python_avatars @mobilesound2112 says:

    I'm waiting for the little Mr Rodger train to come out.

  28. Avataaar/Circle Created with python_avatars @user-rn8ui2ro8c says:

    Have been watching and liking your channel for looong time. Keep being unsubscribed almost every other posting of a new video???? Just want you to know this is happening.

  29. Avataaar/Circle Created with python_avatars @dantone1952 says:

    What's with the funeral music 😢😢?

  30. Avataaar/Circle Created with python_avatars @jonstewart4513 says:

    Definitely ditch the piano music. It makes for a displeasurable experience for me as i dont particularly like missing anything due to naptime. The commentary and symphony of the tools are quite enough.

  31. Avataaar/Circle Created with python_avatars @jayc4283 says:

    what's going on with that music? is there a bet going on? some quality trolling? a dentist office? Bob Ross tribute?

  32. Avataaar/Circle Created with python_avatars @cumbrianmale says:

    Ray must have had a copyright infringement notice to subject us to this horrid elevator music

  33. Avataaar/Circle Created with python_avatars @EL-TEL_1974 says:

    What's with the music sounds like lift ( elevator) music 😂

  34. Avataaar/Circle Created with python_avatars @markamcampbell5795 says:

    where is part 3?

  35. Avataaar/Circle Created with python_avatars @markamcampbell5795 says:

    did you remember to take the paper towels out of the intake runners on the head? i got an engine once for free because the guy forgot his rags in the intake runners and couldn't figure out why it wouldn't run. after I fixed it I sold it back to him for the price of the parts.

  36. Avataaar/Circle Created with python_avatars @jwkingsr says:

    😆What's up with the elevator music? REEEEEEEE! 🤣 Are you trolling us, Ray?

  37. Avataaar/Circle Created with python_avatars @xsiveone says:

    I figured it out. You remind me of Bill Harder.

  38. Avataaar/Circle Created with python_avatars @stanbrown5425 says:

    🇺🇲👍

  39. Avataaar/Circle Created with python_avatars @jabberwockytdi8901 says:

    Geez what a lash up of seals , no wonder they like to leak.

  40. Avataaar/Circle Created with python_avatars @Paulscnccreations says:

    I’m sorry Ray but the back ground music is horrendous. If i wanted to fall asleep i would pick this. But i don’t i want to watch the video. Good job.😂

  41. Avataaar/Circle Created with python_avatars @glennsankey7765 says:

    love the content and the new music keep up the good work

  42. Avataaar/Circle Created with python_avatars @alabamabeatauburn says:

    This music and the vibe I got today is the "Bob Ross" of Automotive is Rainman Ray…

  43. Avataaar/Circle Created with python_avatars @stevemcnally7655 says:

    You must have the patience of a saint, the memory of an elephant and the poise of a ballerina to work on that engine! What a job. Well done.

  44. Avataaar/Circle Created with python_avatars @briankiefer856 says:

    in-depth detail….thanks Ray
