The project has come along great! Im cleaning all the parts and reassembling tomorrow. Any suggestions on a DIY intake manifold cleaning?? Its soaking in oven cleaner right now.

Eeeks...oven cleaner is kind of harsh..it's lye (extremely strong base, the same nasty stuff McDonaldsd uses to remove skins from French fries)

Throttle cleaner is pretty good with baked on stuff however whatever carbon is in the manifold will likely stay in there and not do amy harm.

I always thought french fries were skinned before cutting them. Guess potatoes must be a little longer and squarer over there!!

McDonald's sell great bottled water!!

It really depends upon how far you want to go when cleaning items such as the inlet manifold:

Taken to a silly level like I did a couple of years ago, removed all the marks left over from the casting process then a fair few hours with wet-n-dry followed by extensive use of metal polish applied with a dremel and polishing wheel:

Installed it is better than the original lump of oxidised aluminium but is it worth the 80+ hours of work to get it to this level of clean

Well ive got it all put back together and cleaned up. I took it for a test drive after triple checking everything. Performance wise, it runs the same, starts quicker tho. But the dipstick tube still has a light smoking action and oil spewed all over my clean parts (@#$& it lol!) I followed each step given and cleaned any and every part, hose, hole and orifice I came across. I can only think that maybe the oil trap/separator needs replaced not just cleaned and maybe the same with the nipple piece on the turbo hose? Please help!

Did you clean out the drain port into the block, at the bottom of the oil trap?

Yes sir, there were two ports that connected to the oil trap. So I cleaned them out the best I could and the same with the trap....

Definitely clean the PTC nipple near the turbo on the intake tube.

That is where most of the pressure goes. Some drill it a little wider.

Many replace that hose with a "5/8 heater hose. I have done that on two already.

My Turbo Wagon was recent, and I bought blue heater hose to match all the new silicon plumbing.

: "5/8 heater hose is coming around front of the manifold from next to the radiator hose

So that 5/8ths hose coming around the I.m. is the PTC nipple hose? If so what made you want to route it around the front, is there a benefit to it?

Did you follow this 5/8-inch heater hose DIY below:

PS: Cleaning the engine port is OK, better yet, get a hose, connect to the lower port and blow through it, you should hear gurgling sound from the air you blow in.
