Precat removal - How I did it...

[Anonymous]

ok so now i'm panicking   s:shock: :shock: s:shock:  
my previous car was an adorable mgf with which i had the worry of the inevitable head gasket failure which did happen to me  s:cry: :cry: s:cry:   , so i thought  lets go for a reliable and sexy car next a 'toyota ' a nice shiney red roadster which i love to bits  s:P s:P  
is it as inevitable for the precats to fail on my roadster as an hgf on an mg  s:?: :?: s:?:

Ineveitable? Hmmm... I'd say yes, but that could happen at 15K miles or not until 200K miles, so it's a hrad question to answer.

Get them out and be sure, it's the only way. It's not that hard at all, and this is the best place to read how to do it.



Welcome, by the way!  s:D s:D

Let's get one thing into perspective, Iin comparison to K-series Head gasket failure's, the pre-cat issue on the 1ZZ isn't even in the same ballpark...  Its not even nearly as common.

The K series is a great engine, when its working. However its thirst for Head Gaskets is unbelievable.

finally got the manifold off and the precats smashed to bits. however, 3 studs snapped, oh dear. Rang toyota and I was told that I can get the studs, but it will be 2 days. Is there any reason not to use normal bolts?
Want the car on the road asap.  s:? :? s:?

[kanujunkie]

temporarily, you should be fine, just be careful for the depth of the bolt

[philster_d]

Cant you get some better less "sticky" bolts ?

less sticky???

[philster_d]

"3 stuck bolts"  i mean like stainless or rust proof or something

[kanujunkie]

may not help as most of the bolts are heat sealed in. main reason i only say temporarily on the bolts is that the bolts will have disimilar expansion when they're heat soaked which could create problems if they're in long term

[Anonymous]

I'm thinking maybe I should order replacement bolts incase mine snap when my brother is taking the old rusted ones out.

[Anonymous]

Dan, as well as the obvious need for the new gaskets, I wish I'd just ordered the stud as well for both the maifold to head joint and the manifold to the main cat joint.
Much easier and less stressful if you've got everything that you need.
In hindsight I would have ordered everything that would possiably break.  s:idea: :idea: s:idea:

Ding dong the pre cats are gone!  s:D s:D  
Next step powerflow on monday.
Then unichip in a week or 2.
Would never have known about the precat issue if it wasn't for the club, thanks for all of the advice from everyone.

Just had my precats removed today. The local mechanic i use did it for me for £90 and it took him around 3 1/2 hours. He siad the bolts were no problem at all?

My '2 has 40K on it and the left hand precat had started to crack but no disintegration had occured yet - so i consider myself lucky i got it done when i did.

In the words of robert palmer "some guys get all the luck"
Three studs snapped on mine and put it off the road for a day.  s:cry: :cry: s:cry:

Well I removed the pre-cats last weekend, no broken studs or sheared bolts so I was well happy   s:lol: :lol: s:lol:  Went to Mr 'T' today at Beadles in Gillingham Kent to try and get a manifold gasket - now here's the rub.
Because my car is an import obviously it didn't appear on their computer, so mr parts man ( who was obviously suffering pmt or a hangover ) couldn't decide which of the two types of gasket I required   s:cry: :cry: s:cry:  He asked me why I was taking the manifold off so I told him the story about pre - cats breaking up blah blah blah and he was having none of it.
He then took great pleasure in telling me the car would never pass an emisions test!!!  s:shock: :shock: s:shock:    s:? :? s:?  
I know he is probably talking a load of 5h1t but can someone please re-assure me about this. Also does anyone know where I can buy these gaskets mail order - i'm not going back up there again - unhelpful or what.
Right lets get these suspension springs off  :wink:  Andi
