Thank the GODS!

I just removed my turbo and exhaust manifold. And if anyone has been following my threads, I have been looking for an easy for for a cracked exhaust manifold, or even a new manifold to replace mine.

You see, I bought my BJ74 in December, knowing it needed two things: a new exhaust manifold - exhaust spews out of the manifold under load and fills the engine bay will diesel soot, not to mention the cab; and also new suspension - OME on the way .

But what I was not aware of was the price of these manifolds - $350 - $750 depending where and when you want them.

So I was doing some wishful thinking and hoped that it wasn't a cracked manifold when I noticed two exhaust manifold bolts missing. I finally tackled it yesterday and I had to drill out a broken bolt, and replace two bolts. I thought that this would fix my spewing problems, but no to avail.

So if all the bolts are snug, I only have two options left - a blown gasket or a blown manifold. And to my surprise and unmeasurable relief it was a BLOWN GASKET. FEWF!!!! $30 in parts, $100 in tools, a bunch of cuss words and two bloody knuckles and I have found my problem. I hope.

I purchased my new gasket today and I will put it in on saturday and put the truck back together too, and yes, I will keep you all posted.

I love, love, love my BJ74. I can't wait to drive it on saturday without the constant 'ft ft ft ft ft' sound of exhaust leaking through the manifold gasket.

Thanks for listening.

PS. Im a student, so saving $1100 in parts in labour (doing the labour myself, and not having to buy a new manifold) is equivalent to about 2.5 months worth of paychecks = HUGE DEAL.

Plus the satisfaction of doing it yourself.

Good job!

you want to make sure the manifold face (where the gasket sits) hasnt warped in the time its been leaking, if it has it wont seal 100% and you will need to get it machined.

good luck

Thanks Maat. Will I be able to tell by eye? or Do I need a feeler bar or a special measuring tool to verify?

Place it on a flat surface and look for "light" around the flanges

or use a long steel rule and place it across all the flanges and look for "light"

if you can see 'light' its probably warped, i'm not sure how much it too much 'light' if its only a little bit you may get away with it.

You could also way use a bit of silicone to seal it
(it's a bit ghetto doing that way though)

I went to put Chewy back together today. The manifold is in great shape, so no machining needed. While putting the manifold on, I realized why it was so hard for the mechanic to put in the two missing exhaust bolts - both holes are cross threaded. I didn't want to risk snapping another bolt in the head, so I'm off to NAPA tomorrow morning for a 10M 1.25 tap and chase out the threads. Chewy should be back together by tomorrow afternoon WITHOUT the 'ft ft ft ft ft' coming from the exhaust manifold. Can't wait.

 

[torqueluvr]

Everything is back together. I tapped that (that's what she said) cross threaded hole and got some new studs and nuts from Toyota, thanks to the P/N registry in this forum. As I was putting things back together, I over torqued a banjo bolt - thanks John from Radd for the terminology and p/n - and now I'm on the hunt. No Toyota dealer has it, so I'll try 4 wheel auto on monday, if not, I'll order from Toyota. Thanks for reading!

1st toyota will save you money in most cases

good job keep it running - it has the 13B-T in it or the 3B?

 

[torqueluvr]

13B-T. Next on the list is to up the boost on the turbo. It's stock, to my knowledge.

 

[torqueluvr]

Got the banjo bolt and exhaust pipe clamp this morning, and ooooh baby does she purr. No more siv-like sounding truck.

Thanks for listening,
