Thank you so much for the kind works. Like many jobs it just takes a little patients and a bit of double checking to do correctly. Thanks for watching!
I had to get creative with a breaker bar and some extra leverage with a jack handle. Once they broke loose they came out no problem. Thought this one was a fluke with the stuck bolts. Let me know how you make out getting yours apart. Thanks for watching!
Only question..I’ve done the same thing you did keeping the chains on the sprocket except used rubber bands. Zip ties would be so much easier but how did you get them off once you had everything in place?
Out of curiosity, what part did you use for the timing cover gasket? Felpro TCS46003 or TCS46000? Which one would you go with? One of the parts come with RTV, is RTV a good idea or bad? I have a timing cover gasket that is leaking coolant.
I'm not sure what gasket I used. As for RTV, RTV is fine as long as it is not gobbed on. Too much will get into the engine and cause a whole lot of issues including clogging the oil pump pick up tube.
ivw watched several teardown videos now of the 3.7 and 4.7 and i think now i have enough knowledge to finally redo the head gaskets on the liberty 3.7 happy you shared some tips and tricks for removing and putting them back on and the zip tie method of holding the chain is a great idea i do have 1 question we did just get the jeep liberty has about 190k on it do you need to replace the timing chains or is just a better idea to go ahead and do it anyway since your in there????
Glad i was able to fill in some blanks. It really is pretty straightforward. As for the chains, its a lot of work to get that far. I know the kit can be pricey but i would replace them if they have not yet if you plan to keep the car for a while longer. Also, make sure you replace the oil after all the work. A lot of debris gets into the pan.
You make it look easy! Hey, question; were the heads on that replaced previously by chance? They're awfully clean. Any indication the top end has been apart before?
Well, that's the idea, right. Make it easy. But really the scary part is just seeing all the stuff that needs to be removed first. I'm not exactly sure, but the heads did look rebuilt. They had a nice rattle can finish. lol
@@christopherlitton696 yes, if you have a failed head gasket, the compression is basically blowing by the broken piece of gasket and can go into the water jacket, thus creating bubbles in your cooling system. That's also fuel and air mixture from the intake that's going into your coolant too. The 4.7's are overhead cam engines, so the timing chain sprockets need to be removed. I just did one earlier this year. A bit of a learning curve but I was successful!
@@christopherlitton696 you said "boil". Yes, I've had failed head gaskets where the heat from the cylinder transfers into the coolant, and it can't cool it down quick enough. Keep in mind too, that the coolant system needs to be pressurized to raise the boiling point of coolant. It can't do that when a broken gasket is introducing cylinder gas into it. ALSO****I've had cracked cylinder heads from an overheating engine. The head gaskets were fine, but again, the cooling system wasn't sealed and oil even leaked through.....the cracks would expand the more I drove, thus the overheating symptom got progressively worse the hotter it got.
To replace the headgasket on one of these, the cost depends on your location and labor rate. But Id say a good estimate is between $1,300 and $1450.00. Hope this helps.
