wrecks 2020 Posted August 16, 2017 Share Posted August 16, 2017 Gday all. I bought an '05 GT wagon a month ago and the turbo promptly blew. I replaced it last week with a new one and discovered to my horror that there was no oil pressure to the turbo feed and ACVS lines. The engine runs fine, there is oil pressure but not to the port on the head where the turbo oil feed is. Anyone ever come across this issue? I'm thinking of a temporary feed off the sender switch port and then running engine flush to try to clear whatever is blocking it. Any thoughts? thanks Link to comment Share on other sites More sharing options...
MoarBoost Posted August 16, 2017 Share Posted August 16, 2017 noob teaching the noob! I get to relay what I've just been learning! yay! Seems like the filters in the oil feed banjo bolts can clog up pretty quickly and contribute to low oil pressure. It's recommended that they get removed and that oil is monitored closely and changed every 3k miles. Also, depending on how your turbo "blew" you may have a lot bigger problems. I just had precisely this problem and have been keeping up a thread on my progress. Also, there are a ton of other informative posts about turbo failure. I'd recommend starting by spending a few nights just reading through some threads on here (if you haven't already) Link to comment Share on other sites More sharing options...
Max Capacity Posted August 16, 2017 Share Posted August 16, 2017 New guy has learned, remove the filter from the banjo bolt on the back of the passenger side head. How bad the old turbo blow ? You most likely have metal in your oil system. There's a few things you need to do.

cseagle08 Posted August 16, 2017 Share Posted August 16, 2017 I'm glad I bought my legacy with the engine already blown. At least I knew what I was getting into haha. Link to comment Share on other sites More sharing options...

relative4 Posted August 17, 2017 Share Posted August 17, 2017 As yet it appears nobody has spelled it out: a blown turbo can and often will dump shrapnel into the oil supply. In the case of the turbo you just blew, that may not have happened because apparently it was not being included in the oil supply. But what about the previous turbo? A completely clogged banjo filter is relatively rare, and yours - and/or other oil passages - may be clogged by pieces of the previous turbo. Before installing yet another turbo, it's a really good idea to pull the oil pan and check for glitter. Link to comment Share on other sites More sharing options...
wrecks 2020 Posted August 17, 2017 Author Share Posted August 17, 2017 Apparently no one read my post thoroughly. I REMOVED the banjo bolts (both turbo feed and ACVS) before testing for oil pressure. There is no oil coming out of the port even with engine running. It has nothing to do with the oil screen because IT'S NOT THERE ANYMORE! My question was why is the port not putting out any oil?

JmP6889928 Posted August 17, 2017 Share Posted August 17, 2017 Apparently YOU didn't read what was told to you. There is a banjo bolt on the back of the PS head that HAS A FILTER IN IT AND IT'S THE MAIN FEED TO BOTH OF THOSE LOCATIONS. I read your post thoroughly and told you what to do. You need to ask if you don't understand something rather than putting out an accusatory tone. There are a LOT of people on this forum with a LOT of information and a LOT of experience and they are ALL willing to help you. Being a jackass won't get you very far.

wrecks 2020 Posted August 17, 2017 Author Share Posted August 17, 2017 Ur the jackass buddy. I removed the bloody banjo bolt and screen BEFORE testing for oil pressure. Did you not read that part? Sent from my SM-G920W8 using Tapatalk Link to comment Share on other sites More sharing options...
gkinslow Posted August 17, 2017 Share Posted August 17, 2017 My money is on oil passage being blocked by debris from your initial blown turbo. FYI your first post doesn't mention removing the filter the lies within the banjo bolts. Have you sent off an oil sample to be analyzed? Have you dropped the oil pan and inspected for glitter??

JmP6889928 Posted August 18, 2017 Share Posted August 18, 2017 No you didn't. I'm trying to save your turbo and engine. Post a photo of the banjo bolt from the back of the PS head. You took the banjo bolt out of top of the turbo and top of your AVCS as per your post. There are 2 banjo bolts with filters and your own post says you didn't take either one out. When it pops again and takes the shortblock with it, THEN you'll find them. Link to comment Share on other sites More sharing options...

My question is simply this: Has anyone come across plugged oil passages on these heads? Why would I bother posting pics of the screen when it has been physically REMOVED from the head and is not functional? It is actually part of the banjo bolt as you should well know. I removed BOTH banjo bolts FYI, and neither one is plugged. I'm not going to run the engine with no oil pressure to the turbo, I simply want to know if there is a history of plugged passages and if so is there a solution?

Max Capacity Posted August 18, 2017 Share Posted August 18, 2017 No history of plugged oil passage in the head. If you can, blow air back through the turbo oil feed line. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

Infosecdad Posted August 18, 2017 Share Posted August 18, 2017 ...and discovered to my horror that there was no oil pressure to the turbo feed and ACVS lines. The engine runs fine, there is oil pressure but not to the port on the head where the turbo oil feed is... Can you explain what you did to test this? Honestly, if there is no oil coming out of the port on the head that feeds the ACVS/Turbo, it sounds like you need to pull the heads, oil pan, etc. Especially if a turbo has already died.

robburns201 Posted August 18, 2017 Share Posted August 18, 2017 Just take out the Banjo bolt filter out already!!! And if you take the Banjo bolt filter out that might help! OR replace the banjo filter with a new one! Link to comment Share on other sites More sharing options...

1-3-2-4 Posted August 18, 2017 Share Posted August 18, 2017 Turbo banjo filter is clogged. DO NOT RUN THE ENGINE UNTIL YOU GET IT OUT OF THERE OR YOU'LL BLOW THE NEW ONE TOO! This!! I learned the hard way.. replacement turbo went in under 500 miles.. I missed the banjo bolt behind the passenger head.. I held it up to the sun and you could only see maybe like 8 little dots of light and the rest of it was brown/black and clogged. Link to comment Share on other sites More sharing options...
robburns201 Posted August 24, 2017 Share Posted August 24, 2017 So if I replace oil lines to the braided ones I just use the STOCK banjo bolt?? Sent from my 0PJA2 using Tapatalk Link to comment Share on other sites More sharing options...
